Thank you very much to all those who responded to my post about my problem
with Zmodem on a Sparcstation 2. The following are some of the responses:

Thanks Joe (cool name :-) This suggestion works like a charm. Now, I just
alias the "sz" to "/usr/local/bin/sz -l 1024 \!*" and everything just works!

Hmmmm ... not being a serial communication expert (or even close), this
sounds kinda brain dead to me. Is this suppose to be the case? Is there a
patch if this is an actual "problem"? Please enlighten me.

Thanks again. You have been a most helpful bunch.
