  We're having lots of problems trying to transfer data from one RT
to another over telephone lines - can anybody help?  We're using the
standup RTs, running AIX 2.2.1, with Telebit T1600 modems at each
end.  We've tried using IBM's ATE program, but the XMODEM facility
doesn't seem to work.  We then tried the ZModem 'rz' and 'sz' programs,
both with ATE and with PComm (a public domain telecommunications
program modeled after ProComm).  Short files are transferred fine,
but longer ones inevitably suffer a CRC error, and neither the sender
nor receiver seems to notice and call the transfer off; the machines
just sit there and do nothing.  I've fiddled with the code a bit,
and managed at one point to get almost all of a file transferred
correctly - but when the last, smaller-than-normal-sized packet was
sent, it wouldn't be received correctly and again things would hang up.

  In short, we're stumped.  If you can tell me how YOU successfully
transfer files with a setup similar to ours, I'd be very happy to
hear from you - at least that way I'll know where I should spend all
my time and effort.  Thanks in advance.
