Need help getting xmodem going

[Richard J. Gill]

I am in the process of transfering about 30MB of data from a
CP/M machine to an NCR Tower (Sys V). (Thanks for the responses
to <119 at gillxp> regarding the transfer methodology.) Based on
your comments, and on the commercial availabilty of an xmodem
(a.k.a. modem7 ?) product for the Televideo 816 ("Lync" from
Norton-Lambert), I have concluded that this is the transfer
approach most likely to produce the desired results within my
lifetime.

I picked up a PD copy of xmodem from rpp386 (thanks, john) and
have successfully compiled it on my Tower; best of all, it
actually runs and shows me options to send and receive in
various formats.

It is not clear, however, exactly how it works.  Is it expecting
the other system to login and execute it (ala uucp)?  How do I
establish the communication with the other system?  The commands
lead me to believe that either end can initiate a file copy, but
none of the options displayed refer to establishing a
communication link. How do I do it?

For testing, I have a clone PC available which has "PC Works"
installed on it; that product claims to support xmodem file
transfers. How do I test the software on the Tower to make sure
it will work when we are ready to do the  "real" transfer?  As
you might guess, my knowledge of the PC world and protocols like
xmodem is sparse, so any thoughts or guidance will be
appreciated.

Thanks for your help.
