I use rz/sz and a DOS program called TELIX together with no problems at all.

The rz/sz came with the system (NCR Tower 800 running SYS Vr3).  TELIX
is a general purpose tele-comm program. similar to (but much superior IMHO)
Procomm.  

I have got transmittions to work over direct-link at 38400, with very few
retries or NACks or any problems at all.

I have got it to work with still as few problems using USRobotics modems
at 9600.

I did try DSZ once (a demo copy) and I didn't really like it so I stuck with
TELIX.
