~B AB

This  command is only appropriate when used in a script file.  See your manual 
for details.

~End



~B AC

The   ACcept   command   allows you to set the type of access a  caller   has  
when  calling  into an answering CROSSTALK system.   By  setting  the  access 
level,   you  can   protect  your system from unauthorized  tampering.    The  
options  to  the ACcept command are:

Option    Action
--------  -------------------------------------------------------
Nothing - Prohibit caller  from writing to any files 
Appends - Allows    caller    to   append  captured  data  to   an    existing
          file, but not to create  any new files.  
Creates - Allows    caller   to  append  data  to  or  create    new    files,
          but  not to overwrite existing files.
Everything  - Allows caller full access to system.  
~End

~B AN

     The  ANsback  command  tells  CROSSTALK whether  or  not  to respond   to
a received ^E character.    Many  computer   networks  utilize   this  feature
as  a  means  of identifying  a  caller.   Answering CROSSTALK and TRANSPORTER
systems utilize the feature to request  your password.    If ANsback is ON,  a
received  ^E  will cause  the contents of your F4 key (see FK command) to   be
sent.   If ANsback is  OFF, the ^E will be ignored.
~End

~B AT

     The    ATTENTION  command   selects   the  key  to  be  used  for    the  
Š"ATTENTION"   key.    The  attention  key is the key used  to   display   the  
"Command?"   prompt when you are in  terminal  mode.      Note  that this key 
can  not be sent  to   the remote computer,     since  typing it  causes  the 
program  to  immediately  enter the  command  mode.     The  default key used 
for attention is a CONTROL-A (^A).   If  the  system you are calling requires 
you  to   send a CONTROL-A,  you  will have  to  select another key  for  the  
attention key. 

Note   that  CROSSTALK  will not allow you to set the  ATTENTION,  BREAK  and 
SWITCH  keys to the same key setting.
~End

~B BK

     The   BKSIZE   command    sets   the   size  of   the   data   block (in 
256     byte   increments)   sent   during    protocol  transfers.    It   is  
normally   set  to 1.     If  you  are  "direct connecting"   two   computers 
together without modems,     you  may wish  to  select   a  larger block size 
(up  to  16).      Using    a  larger   block   size  marginally   speeds  up  
protocol    transfers.     We   recommend   the  default setting  of  1  when  
transferring  files via modems.
~End

~B BL

     The  BLANKEX command tells CROSSTALK how to  handle  "blank" lines  when  
sending  files  to another computer  with  the  SEnd command.     If  BLankex 
is  ON,   CROSSTALK  will convert blank lines into  lines consisting  of  one 
space.     This  may  be  useful  when sending  prepared   text    containing  
empty   lines   into  a  host computer system which assumes a blank  line  to 
mean "end of text".  
~End

~B BR

     The   BReak  command is used to select the key to be used for sending  a  
BREAK.  The BReak   key is normally assigned to be a CONTROL-B (^B),  but may 
be changed  if desired.   
~End

~B BY

     The  BYe command hangs up the phone line,    and disconnects the current  
call.  Use  this  command  when you wish to hang  up and  make  another  call  
without exiting CROSSTALK.
~End

~B CA

     The  CApture  command has two  main  modes:      Capture-to-disk,    and 
capture-to-memory.    To capture directly to disk,    enter "CA  (filename)".  
If the file already exists,  CROSSTALK will ask if you wish to over-write the 
file,  or append the new data to the end of the old file.  The command "CA -" 
is used to to end capture-to-disk, and closes the capture file.

Š     To  capture  data  to  memory,      enter  "CA  +".      Capture-to-disk  
automatically stores the captured  data   to the  specified  disk file,   but 
capture-to-memory  requires  that  you   use   the WRITE command to save  the  
data  before   exiting  CROSSTALK.   While   capturing data,     the  command  
"CA  /"   will toggle  capture  on and  off,  allowing   you  to  selectively  
save incoming data.   The command "CA -"  turns capture OFF.   

     If   you  wish to capture some data which is already  on   your  screen,
and   capture  is OFF,    you may use the  "RETRO-CAPTURE"  feature.    Enter 
"CA  <xx",  where  xx is the  number  of  lines you wish to "grab"  off   the  
screen.     CROSSTALK  will retroactively  capture  the data,   add it to the 
capture    buffer,    and  leave CApture ON.   RETRO-CAPTURE my only be  used 
when CApture is OFF.
~End

~B CALL

To make a call, follow these steps:

     1. Enter the phone number with the NUMBER command.
     2. Select a modem speed with the SPEED command
     3. Enter "GO", or press ENTER at the "Command ?" prompt.
     4. When you are connected, CROSSTALK will let you know.
     5. To disconnect, press ESC, then enter "BYE" at the "Command ?" prompt.

~END

~B CO

     The   COMMAND command  sets  the  COmmand key.     The COmmand character  
is    the    key  a  caller   would  type   if  he   had  called   into  your 
system  and  wanted   to enter   commands    to  CROSSTALK.      We recommend 
that you leave this key  set to  the default setting of ^C.
~End

~B CS

     The   CStat  command has two functions.    The  command   "CStat"  alone  
displays the status of the capture buffer  - how many characters (in K)  have
been captured, and how much space is still available for capturing.

     The command "CS fred" will search the capture buffer for all  occurances 
of  the text "fred".    If the word "fred" is located in the capture  buffer,  
the  program will display the contents of the capture  buffer surrounding the 
located  word.    After   displaying the  word,   the program will  offer  to 
continue searching  through the buffer.

~END

~B CW

Š     The  CWait  command  tells  CROSSTALK how  to  wait  between  characters  
when  transmitting files with the SEnd command.     Use this command when you 
are  sending  text  to a computer system which can not accept  text  at  full 
speed.

     The  CWAIT command has several  options.   The  chart  below illustrates 
the effect of each:

Option    Effect
NONE      Do not  wait at all   
Echo      Wait for each character to be echoed by the host before 
          sending the next character 
Delay  XX Delay  xx  1/100 of a second,   then  send  the  next 
          character.

     Note  that  CWAIT can be used in combination with  LWAIT  to allow   you  
to  transmit text to virtually any  dial-up  computer system.
~End

~B DA

The DATA command is used to select the number of data bits used by CROSSTALK.  
The  default value  is   8.   CROSSTALK automatically   switches to  8   bits
whenever  a  protocol  transfer  is   performed,      even  if  7  bits   had 
previously  been  selected.  Most dial-up computer systems require   7   data 
bits.
~End

~B DE

     The     DEbug    command  allows you to select one  of   three   "debug"  
modes.    The  debug  modes  allow you to display incoming control-characters  
graphically  on your screen.   This  is  often useful   when   attempting  to  
identify    non-printing    control characters transmitted  by  some  dial-up 
computer systems.

     The chart below shows how each of the debug modes operates:

Mode      Action
NONE      Incoming control characters are not altered.

HEX       All   incoming   characters  are  shown  as  hex    numbers.    For
          example, an incoming ^Z will be shown as [1A].

CHAR      Incoming  control-characters are shown in the form  ^X.  
~ENd

~B DI

     The   DIr command is used to view the disk  directory,    much like  the 
CP/M "DIR" command.    Like the CP/M DIR command, you may provide an optional 
file name,   and the program will display only those  files given in the file 
name.   For example,  the  command "DIR *.ASM" will show only the .ASM files.

     There    are  two options to the DIr command  which  are  not found   in 
Šthe CP/M DIR command.  These are the /S and /T options.  The command "DIR /S" 
will show  the size of each file,   and "DIR /T" will show the amount of time 
required to send each file,   at the current speed.   

~END

~B DO

The DO command instructs CROSSTALK to perform the commands contained  in    a 
"script"    file.    Script   files   are    files  containing  commands  for 
CROSSTALK to perform.  There  are three forms of the DO command.    The table  
below shows how each works.

Command        Action:
DO             When   no   other  script  file  is  active,    this   command
               will   display   a  menu  of  the  available   script   files,
               and   then  ask  you  to  choose  one.     The  chosen    file
               will then be performed.

DO             If    a   script   file  has  been  suspended  by    a    WAIT
               MANUAL    command,    entering    "DO"   will    resume    the
               script file processing.

DO BERT        Performs the script file "BERT.XTS".

You  may  create a script file with any text editor,  such as the ED  program 
which is included with CP/M.   Script files must have the file name extension 
".XTS".   The  script  files  may contain any list of commands  you  wish  for 
CROSSTALK to do.  The commands "REply" and "WAit" are especially useful.
~END


~B DP

     The  DPREFIX command tells CROSSTALK how to dial your modem.   When  you 
instruct  CROSSTALK  to dial,  the program sends the following  data  to  the 
modem:

       DPREFIX string  | NUMBER string  |  DSUFFIX string

     By changing the DPREFIX string, CROSSTALK can dial a number of different 
types  of auto-dial modems.   There are several characters which have special 
meaning when placed in a DPREFIX string.  These are:

Character      Effect
   |           Places a carriage return (ENTER key) in the string.
   ~           Causes CROSSTALK to delay one second when dialing.
   ^           The  character following the ^ character is sent as a  control 
               character.   For example, "^T" would place the ^T character in 
               the dial prefix.
~END


~B DR

Š     The DRive command has two functions.  Entering "DRive" alone will simply
"log in" the current disk.  This is necessary if you change  diskettes  while
in CROSSTALK.  Entering "DR" followed by a drive name ("DR B:") will both log
in the diskettes, and change your "default" drive to the specified drive.

     Wheî  "DRive¢ ió issueä froí terminaì mode¬  thå disketteó wilì  bå  re-
logged and the amount of space on the current disk will be displayed.

     Note that CROSSTALK can not tell which drives actually have diskettes in 
them.  If  you  try  to set your default drive to a non-existent drive, or if 
there  is  no  diskette  in the selected drive, CP/M will give you a "SELECT" 
or "BDOS" error,  and CROSSTALK will most likely leave you in CP/M,  with  no 
way to recover any captured data.
~END

~B DS

     The DSUFFIX command sets the dialing suffix string.  (see explanation of 
the DPREFIX command).   The same special characters apply to DSUFFIX as apply 
to DPREFIX.
~END

~B DU

     The  DUplex command  sets duplex to full (local echo OFF) or half (local
echo ON).    Most  dial-up computer systems  require that your system be  set
for  FULL duplex.

Note that when you select ANSWER mode,  CROSSTALK selects HALF duplex.   When 
you select CALL mode,   the program automatically selects FULL duplex.    See 
the glossary for an explanation  of "duplex".
~END

~B ER

     The   ERase   command has two functions:   The command  "ER" alone  will  
erase   the contents  of the  capture  buffer.     The command "ER  FILE.NAM" 
will erase  the file   "FILE.NAM".    You  are   always  asked to confirm  an  
erase  before  the  operation  actually  takes place, unless you use the "/Y" 
option in CROSSTALK (i.e.- "er file.nam /y").  Be careful when using /Y after 
an  ER command,  as  there is  no  way  to  recover  the erased  information.  
The  command  "ER *.*" will allow  you  to selectively erase any or all files 
on a disk. 

     Note  that  an  answer-mode caller may only  use  the  ERASE command  to 
erase  the contents of the capture buffer.    He may NOT erase files from the 
disk.
~END

~B FI

	The   FIlter  command is used to select  which  characters  CROSSTALK  
will  discard  when  the INfilter option is used.    Enter "FI"   and   press 
ENTER, and CROSSTALK will show you a list of "PASSED" and "FILTERED"  control
characters.  You may change the list as  desired for  your application.  Note 
Šthat  the  FIlter settings are  saved when a command file is saved  with  the 
SAVE command.
~END



~B FK
     The    FKeys   command  is  used  to  set  and  display   the   contents 
of  the  programmable  function  keys.     The  command "FK"  will  show  the 
settings  of the function keys.

     To set a function key, enter "FK n string", where n is the number of the 
key  to  be  set,   and  "string" is the string of text assigned to that key.
Several  characters  have  special  meaning  when used in function keys.  The  
vertical bar (|) places a carriage return in the string. The tilde (~) causes
a one second delay.  Any key which begins with an at-sign  (@)  will be taken
as a command  to CROSSTALK.  

     Foò Example¬ thå commanä "FË ± @PÒ  /|¢ wilì seô keù ± tï "@PÒ /|"® Wheî 
keù ± ió pressed¬  CROSSTALË wilì togglå thå printeò oî oò off.
~END

~B GENERAL

If  you  wish to make a call,  enter "HELP CALL".   If you wish to  exit  from 
CROSSTALK,  enter  "QUIT".   For  help  on any  specific  topic,  enter  "HELP 
(topic)".  
~END


~B GO

     The  function  of the GO command depends on which  mode  the program  is
in.   In  CALL mode,  The  GO  command tells CROSSTALK to  dial  a number and
establish  a   connection.  You   may  instruct  the   program   to   re-dial
automatically  if  a  connection  is   not established   on the   first  try.
The  command "GO R30"  would tell  CROSSTALK   to re-dial every  30   seconds 
until a  connection is established.  Similarly, the command "GO R30/60" would 
instruct  CROSSTALK to re-dial every 30 seconds while waiting 60 seconds each 
time it dialed for connection.

     The   command   "GO  LOCAL" tells CROSSTALK that  there   is   no  modem  
connected   to  the system.     Use  this option  when  using  CROSSTALK   to 
transfer  files between  two computers  "hard-wired" together.      When  the 
local option is used,   the carrier detect  signal  on  the RS-232  interface 
is ignored.

     IN  ANSWER  mode,  the GO command tells CROSSTALK  to  begin waiting for 
incoming calls.
~END

~B HE

     The   HELP  command  provides  help  on  all  of  CROSSTALK's  commands. 
Entering   "HElp"  with   no option displays a  list of  all  of  CROSSTALK's 
Šcommands.   If you need help with  a  command,  type  "HELP  XX" <CR>,  where 
"XX"  is  the  command you  need  help  with.     If  CROSSTALK  asks  you  a 
question you don't  understand,   enter  a "?", and the help for that command 
will be displayed.
~END

~B IN
     The  INfilter  command  tells  CROSSTALK  to  discard  incoming  control 
characters  when  in terminal mode.    Some host  computer systems  may  send 
control-characters which are meaningless to your computer.  Turning  INfilter  
ON  will discard these characters.  If your see extraneous "junk"  characters  
on the terminal screen,  try turning INfilter ON. INfilter also "strips"  the  
top  bit off of 8-bit characters.  With INFILTER OFF,  these characters   may  
appear   as  "graphics"   characters.  Turning INFILTER ON will display these 
characters correctly.

~B LF

     When  LFauto  is on,    CROSSTALK will print a line feed on  the  screen  
after    each  received   carriage   return.      This    is   useful    when  
communicating  with systems which do not send line feeds.

     Conversely,   when   LFAUTO  is ON,   CROSSTALK  will  print  a carriage  
return   each   time  a  line feed is   received.    This   is  useful   when  
communicating with systems which  send  line  feeds without carriage returns.
~END

~B LI

     The  LIST  command  is  used  to display CROSSTALK's parameter  settings
to  a calling system when your CROSSTALK is in answer mode.  This command has
no effect when issued locally, and will not generate an error.
~END

~B LO
     The   LOad command is used to load CROSSTALK  command  files.    Command 
files   are files  containing  commands  for CROSSTALK   to  perform.     The 
command   "LO"   will  display  all of the available  command   files,    and  
allow  you to choose  one  to  load.     The command "LO  FRED" will load  in 
"FRED.XTK",  and perform  all  of  the  commands  contained in that file.    
~END

~B LW
Š
     The   LWait  command  tells CROSSTALK how to  wait  between  lines  when 
transmitting text  files with the SEnd command.     There are several options 
to the LWAIT command.   The table below shows how each option works:

Option         Effect
NONE           Each line is sent with no waiting.
Prompt X       Send    a   line   of  text,    wait  for  a   prompt   of   X
               characters, then send the next line.
Char "X"       Send   a  line  of  text,    wait  until  the  character   "X"
               is received, then send the next line.
Delay X        Wait X tenths of seconds between lines.
Manual         Prompts    the    user    to  press    space    bar    between
               each line.
Echo           Wait    until   a  carriage  return  is  echoed    from    the
               host system.
Learn          Send    the    first   line   of    text,    count    incoming
               characters,  wait until the user presses the space bar,   then 
               send  each  successive  line  with a  wait  for  a  prompt  of  
               "count"  characters.

~END

~B MO

     The   MOde   command tells your CROSSTALK program  whether  to  Make  or 
Answer  calls.   If  you wish to MAKE a  call,   select  "CALL"  mode.     To
ANSWER  calls,    use  "ANSWER"   mode.     CROSSTALK  automatically  selects 
HALF Duplex (see DUplex command)  when the  answer  mode  is  selected,   and 
selects FULL duplex when   call  mode  is selected.
~END

~B NA

     The    NAme   command   is used to set the name of  a  called  location.
Use   of  this command    is  optional.     If a NAme has   been   given   to 
CROSSTALK,    the name will  be  sent  as  a "greeting"  message  whenever  a  
remote  terminal    calls  into CROSSTALK in the answer mode.
~END

~B NO

     This   command  is  used  internally  between  two   CROSSTALK  systems.
It   is  sent  from an answer system to a call system  at the end of  a  file 
transfer,  to  tell  the calling system that there are no more  files  to  be 
transmitted.

This command is not normally entered as a command by the user.
~END

~B NU

     The    NUmber   command   sets the phone number to   be   dialed.    The 
number may be up to 35 characters long.  
~END
Š
~B OU

     The  OUtfilter   command   instructs  CROSSTALK to   screen   out   line
feed  when sending text files with the SEnd command.     If OUtfilter is  ON, 
line feeds characters are discarded. 
~END

~B PA

     The     PArity    command  is  used  to  set  the  parity  bit  to   the  
appropriate   value.   Some  systems  require  that parity be  set correctly,
other   systems   ignore  parity  entirely.     The possible settings for the 
PARITY command are None, Even, and Odd.
~END

~B PR
     The   PRinter  command  tells  CROSSTALK  to  echo  all  data  displayed  
on   the  terminal screen   to  the  printer.    Turning PRinter  ON does not 
turn the  terminal  video display off.    The command  "PR /" will toggle the 
printer to the opposite state  of what  it  currently  is.   

     Notå  thaô trip-keù Ð wilì alsï togglå thå statå oæ thå printeò froí  oî �

~END

~B PW
     The    PWord  command  is  used  to  set  CROSSTALK's  answer  password.
The   password may  be  up  to 12  characters  long.    If  you  have set   a  
password,    then  any persons calling  into your  system will be required to 
enter the password  before  they  can   access your system.     Setting PWord 
to blank disables  the  password feature.

~B QU

     The     QUit     command   tells  CROSSTALK  to   immediately disconnect  
and   return   to  DOS.    If any  information is in   the  capture   buffer,
CROSSTALK  will ask if you wish  to  save  the information before exiting. 
~END

~B RC

     This  command is used internally by CROSSTALK,   during  file transfers. 
It is not normally entered as a command by the user.  
~END

~END

Š~B RE

     The    REply   command  sends a string of text  to  the    modem.    The  
command   "RE Hello."  would  send  the  text "Hello." to the   modem.     To  
send  a  control character,  enter the character in the form "^X".    To send 
a  carriage  return,  use the vertical bar "|".      The  REply   command  is 
normally used only  inside  of  a  CROSSTALK   "script"  file.   Script files 
are  a  special  type   of  file  which contains commands  for  CROSSTALK  to 
perform.   See chapter 12 for more information on the REply command.
~END

~B RQ

     The    RQuest    command  is used to request  a   transfer    of   files  
from  another CROSSTALK  system.  This command should only be  issued  from a 
CALL mode system when calling into  an  ANSWER mode system.
 
     You  may  specify  an  optional target or destination  drive  name  when 
issuing the RQUEST command.  Some examples of this are shown below:

Command        Result
RQ *.asm       Request all files with the type .ASM

RQ  B:FRED     Request  the  file FRED from drive B:,  place  the file on the 
               default drive.

RQ  B:BERT C:  Request   the  file BERT from drive B:,   place  the  file  on 
               drive C:.

~END

~B RX
	The  RXMODEM command is used to receive files from  another  computer  
system using the XMODEM protocol.    To transfer a  file from  another system 
to yours,   first tell the other computer  to send  you  a  file,  then press 
the attention key and  enter  the command "RX (filename)"
~END

~B SA

     The    SAve    command  saves  a CROSSTALK  command  file   for   future  
use.   All  of CROSSTALK's operating parameters,  including all function  key 
definitions,  are saved in the command file.  
~END

~B SC

     The  SCreen  command  may  be  used  to switch screens under control of a 
script  file.   The options are "SCreen S" to switch to the status screen, and 
"SCreen T" to switch to the terminal screen.
~End

~B SE

     Use   the   SEnd command to send a text file from your disk  to  another  
Šcomputer system.    This command is most often used  when communicating  with  
another  computer which  is   not    running CROSSTALK.     If the system you 
are communicating with is running CROSSTALK,  use the "XMit" command instead.  

     Several   other   commands  are  used to modify the   method   the  SEND 
command  uses  to  send files.    For information on  all  of   the  commands  
affecting  the  operation  of the SEnd command,    see   the   LWait,  CWait, 
BLankex, and OUtfilter commands.
~END

~B SP

     The  SPeed  command   selects   the  speed  at  which   your    computer
will   communicate  over the phone  line.      Only  the first digit of   the 
desired speed need must be entered. Note that 1200 baud is 1, 110 baud is 0.
~END

~B ST

     The   STop command sets the number of stop bits used to make up the data  
word.   Most systems use 1 stop bit at speeds of  300 baud,  and above, and 2 
stop bits at 110 baud.
~END

~B SW

     The   SWitch   command   selects   the key to  be  used  for   switching  
between the terminal and status screens.     This key is  normally the ESCAPE
key, but can be changed to another key if desired.

~END

~B TA

     The   TAbex  command is used to turn tab expansion on  and  off.    When 
TAbex    is  on,    transmitted tab characters are  sent  as spaces  to   the 
next  tab  position.   This  is useful when  sending files  to systems  which  
do  not interpret tabs. 

     Note  that the TABEX command only affects the SEND  command.   It has no 
effect on normal "terminal mode" operation.

~END

~B TU

     Some   computer   systems use a key other than ENTER  to  mean "end   of  
line".    The  TURNAROUND command tells  CROSSTALK  which character  to  send 
when the ENTER key is pressed.  
Š~END

~B TY

     The  TYPE  command  has  two functions:  It may be used  to  review  the 
contents of the capture buffer,  or it may be used to view the contents of  a 
disk file.

     When    given  with no name,    the TYpe  command   types  the  contents  
of   the capture buffer  to  the screen.     The  command "TYpe   (filename)"  
will  type the contents of the  file  on  the screen.

~B UC

     The  Uconly  command is used to set upper case mode  on  and off.   When  
UConly is on,    all  lower case letters encountered during  a  SEnd  will be 
converted   to  upper  case.    Received characters are  unaffected.

~Â WA

     The     WAit   command   tells  CROSSTALK to wait  between   lines  when  
performing  a script file.   The options available with the WAIT command are:

Condition      Effect
Echo           Wait  for  a carriage return,   then do the next line  in  the 
               script file.
Quiet X        Wait     until    the   line   is    "quiet"     (i.e.,     no
               characters  received)  for X tenths of  a  second, then do the 
               next line in the script file.
Delay X        Wait for a period of X tenths of a second, then do 
               the next line.
Char 'x'       Wait    until   the  character  "x"  is  received   from   the 
               communications line, then send the next line.
For 'x'        Same as "char 'x'", above. 
Prompt X       Wait  for  X characters  from  the  communications line,  then 
               do the next line in the file.
String 'xyz..' Wait for the specified string from  the  communications  line. 
               Note that spaces and character case are ignored.
Manual         Suspend script processing until a "DO" command  is issued.

~B WR

     The   WRite command stores  captured data into a file of  your   choice.  
If     a disk  error occurs,   or if the capture buffer is  empty,  an  error 
message will be printed.   

     Use   the  WRITE   command  when you have  captured   data   using   the 
capture-to-memory  command,  and you wish to save the captured data on   your 
disk.    It  is  not  necessary to use the WRITE command  if  you  are  using 
capture-to-disk.

~END

~B XC

     The  XCPM  command  tells CROSSTALK to exit to CP/M  without  hanging up 
the  phone  line.     You may run any other program and return  to CROSSTALK, 
and  your  connection will still be intact.    If any information is  in  the 
capture buffer, CROSSTALK will ask if you wish to save the information before 
exiting. 
~END

~B XM

     The   XMit   command  transmits  files  to  another   CROSSTALK  system.  
"Wildcard"  file names are allowed.     An optional target drive  name may be 
given after the file name.   

     Note   that  the XMIT command should only be used when calling  into  an 
answer-mode CROSSTALK or TRANSPORTER system.

     The chart below shows some example XMIT command:

Command             Action
XMIT *.ASM          Sends   all the files with  the type  .ASM  to the  other 
                    system.

XMIT BERT           Send   the file BERT from the default drive to the  other 
                    system.
Š
XMIT B:FRED C:      Send the file B:FRED to drive C: on the other system.

~END

~B XX

	The  XXMODEM  command is used to send a  file  from  your computer to 
another  system  using  the  XMODEM protocol.    To send a  file   from  your 
computer  to another system running XMODEM,   first tell the other system  to 
prepeare  to receive a file,   then  press the ATTENTION key,  and enter  the 
command: "XX (filename)"
