I have recently attempted to start using zmodem instead of kermit, and am
having some problems.  

Configuration:  amiga 1000 running jrcomm on one side, and a sun4 running 
the 'sz' and 'rz' programs (from uunet.uu.net) on the other side.  

Symptoms:  When downloading files from the sun to amiga, sometimes, near the
end of the transfer, jrcomm seems to escape from the zmodem receive mode,
and so I see a bunch of ^H^H^H ^X^X^X type of garbage on the screen.  I'm then
left with a short file on the amiga.  Doing a zmodem continue dowload gets 
the rest of the file OK.

I've had similar problems with ncomm1.9, which leads me to believe that
it is probably the unix side zmodem program.  Is it the latest zmodem 
available (for that matter, is there any other zmodem available??)?  
Does anyone else have any problems running sz, rz on a sun (possible sparc
alignment problem??).  Are there any flags I should be passing sz? (I'm 
currently just doing a sz <filename>)

Any help is appreciated.
