[net.micro] file transfer while on unix from an rcpm?

gtp@houem.UUCP (G.PECKHAM) (12/27/83)

I need some help in transfering a file from an rcpm system up to unix.
I know that if I am on the rcpm side i can invoke umodem to do the
transfer but don't know how to do it when i am on the unix side.
the cu command allows file diversion if you put a "~>:file"
in the beginning of the file to be transferred but doesn't seem
to work for me if i send the diversion signals and
then a cat to the rcpm (or copy , pip, etc.).
anyone out there know how to do what i want?
Umodem is the preferred method because of the noise
that is picked up during listings.

HELP!
