I'm having trouble getting rz and sz (zmodem) to work properly on a 6150
RT running AIX version 2.2.1.  I've included bsd library with all the
sysv flags on the cc lines in the Makefile and, with that, it will compile and 
run.  ASCII files transfer both ways with no difficulty, but binary files die 
after the last block is sent.  A ^Q sent to the RT will cause it to send
several buffered zmodem acks afer I abort on the other end of the transfer.  
Several ^Xs will stop abort on the RT's end of things.  Basically, the RT is 
behaving as though it received a ^S after the last block is sent.  This 
happens both when sending and receiving with binary files.  These problems do 
not show up when using piped input and output. 
 
Does anybody have an idea what is happening here?

Regards,
Victor

Please post any answers to the above posting since I and another site
downstream of myself are having the same problems with zmodem.  Something
we've found to clue us in to the problem is that everything works fine
on binary files until the RT receive's a NAK.  It acts as though nothin
happened and continues to send.. Again, as Victor mentioned, this does
not happen in piping mode... I wonder if maybe my modem could be the
cause of this problem.  I have an HST and I think the HST has a 1K
buffer... Could this be part of the problem do you think?
