	I'll grant you that "tip" does not hold the user's hand
the way PC programs such as Qmodem and Procomm do, however I know
from personal experience that it is possible to:
	tip from a SUN 3/160 running SUNOS 3.5 to a VAX running Bsd.
	start "sz" (send zmodem) on the VAX to send a file to the SUN.
	use the tip ~ escape (I think it was ~|) to start "rz" (receive zmodem)
		as a sub-program with stdin == tip line, stout = tip line,
		and stderr == the SUN window tip was started in.
It worked like a champ for me when I needed to transfer compressed tar files.
Zmodem gives you lots of progress messages, so you'll know if anything
goes wrong.

	You should have no problem finding Zmodem (rz and sz) at
your neighborhood archive.  There are freely distributable versions.
