-    I'd like to hear about this also.  I have Forsberg's rz and sz compiled
-for ISC Unix rel.2.2  (SysVr3.2) and whenever people call from DOS machines
-and try to download stuff using dsz they get lots of timeouts and error re-
-covery and a very low transfer rate.  My modem is a T2500 with the registers
-optimized (as best I can) for unix/uucp.  Also my rz/sz is fairly old, since
-it's what came as a freebie on the disk Omen Tech sent me when I registered
-dsz-for-DOS a couple of years ago.  Would a newer rz/sz help, or is it my
-modem settings or something else?  My serial card has only a 16450 UART, but
-all the errors happen even at 2400bps, so it doesn't seem that the lack of
-a buffer is the problem.

I got rzsz from Simtel and installed it in my dhome directory under
Ultrix 4.0.  I call here from home and use the rzsz to pass files. I
have absolutely no problems. I compiled it as stated in the archive. I
touched no code or make file. It runs beautifully right out of the
'box'.

Good luck, it sounds like your Unix environment doesn't like the
streaming methodology of Zmodem...
