Looking for ZModem for Xenix

Sat May 25 12:44:21 AEST 1991

I run a small Xenix 386 system at work, and I am involved in doing some
file transfers with several customers.  Currently, all I have is
Columbia University's Kermit, which is rather slow.  If anybody has
source code or binaries of an implementation of ZModem that runs on
Unix/Xenix, or knows how I might get this, I would greatly appreciate
it.  Please reply to me via e-mail, since I rarely read Usenet.
