Bill, 
Still no luck with this. I have re-installed zmodem.  I have deleted alot 
of new stuff on this new machine that seems to be Windows specific as I 
don't really give a hoot about Windows; this freed up some memory, now have 
about 160k free.  Didn't really think it was memory anyway though.  Problem 
seems to only happen with zmodem uploads above 2400bps.  I noticed today 
when I witnessed it happening to a caller after message Error 103 it said 
invalid directory.  It does indeed seem to my uneducated mind to be some 
sort of command line problem.  But what?  I have in my directories a SZ.bat 
and Rz.bat that I have re-installed from scratch from a dsz11214.zip 
archive.  Do I need to modify these or any other batch files in any way?  
It's been a long time since I first installed zmodem.  Any ideas will be 
much appresicated, I6m really pulling my hair out!  I also tried commenting 
out my disk cache and rerunning optimize but this didn't help.
Regards,
