This should run just fine at any speed the PC is capable of.  I use the 
combination here all the time at 19.2kb with zero problems.

No, two totally unrelated matters.  IF you are using Chuck Fornsberg's
rzsz on unix, he uses the standard library fread() and fwrite() calls
to pass characters to the comm stream.  He does not expect to receive
a full block in one fread() and indeed normally gets one.

Before we get all spun up trying to help, you need to give us some 
diagnostic information.  What does the status line show before it
crashes.  And how about running zmodem on the unix system in diagnoistic
mode (-v or verbose mode) and tell us what it says or post the tail 
end of it.  Zmodem is normally bulletproof so either you have a bad
configuration or bad binaries or something similiar.
