The rx/sx entry was inadvertently omitted from the Gulam manual; so
here it is.  Note also that due to a lazy editing error, some shell
vars are listed as ..._command where they should really be ..._cmd.

>> rx/sx -- Xmodem File Transfers     << 

These  are built-in commands.  Rx receives a file from the remote
system;  and  sx  sends  a file to the remote system using Xmodem
protocol.  

        rx fnm 

command  opens/creates  file  fnm  for  writing.   If  the  shell
variable  `rx_remote_cmd'  is set, Gulam constructs a command for
the  remote  system  as  "$rx_remote_cmd   fnm",  and  sends this
command  through  the  rs232  port,  and then awaits the packets.
For  use with our 4xBSD Unix, we set this var to `xm st'.  Unless
the  `xm'  on  the  remote machine is of the quiet type (one that
does  not respond with, say, "Xmodem: Ready to send..."), setting
rx_remote_cmd  actually  prolongs  the first synchronization.  If
this  var  is unset, you should first switch to remote (say using
te  command),  and  issue  the appropriate command to the remote,
and  then  switch  back  to  AtariST  and  the  give  the  rx fnm
command.  

        sx fnm 

is  essentially  similar.   Gulam  opens  fnm  for reading, sends
"$sx_remote_cmd  fnm",  if  that var is set, and awaits the first
sync.  For our 4xBSD Unix, we set sx_remote_cmd to 'xm rt'.  

If  sending/receiving  binary files use 'xm rb' or 'xm sb'.  Note
that  files received with Xmodem usually contain extraneous bytes
at  the  very  end of the file.  With text files, you often see a
bunch of ^Zs.
