       You really want to use uucp to transfer files from one Unix
       machine to another.  It's the standard.  Is there some reason
       why you can't do this?

I do not want to use "uucp" because the it requires disk space for
spool files and human intervention to set up and maintain. In the next
couple of years we expect to have over 2000 microcomputer/workstations
on campus.  Many of those microcomputer/workstations will be Unix
systems with modems and terminal emulation software. The overhead in
maintain uucp links with 1000+ workstations would be to high.

So what I am looking for is a "xmodem" (cf. MDM7xx) program written in
C that will permit a user on a Unix system (eg. a Unix microcomputer)
to dial out to a remote Unix system, login to a remote Unix system (via
terminal access dial-up lines), execute a remote "umodem" program to
start a file transfer, escape back to the local program, and fire up
the local end of the file transfer.
