Wouldn't we all.  My understanding of the state of affairs on serial
communications on the 3000 is that Full Duplex conversations (that is,
the ability to simultaneously send and receive data) is not available.
[I almost said "possible", but then *all* things are possible,
especially in software.  ;]  Since Zmodem (at least in terms of a
sliding window protocol) is dependant on that ability, I expect Zmodem
to be challenging to implement on MPE.
 
Of course, my ignorance of the latest advances in DTC features may cause
all this to be wrong.  If so, I'll gladly admit my error in exchange for
a working full implementation of Zmodem on the 3000.  :)
