I'm having some trouble with ZTERM 0.85 and sz (revisions listed up to
May 1989).  ZTERM works fine as a terminal emulator, but when I type
"sz filename", the zmodem receive window pops up and then just sits
there.  After a while I hit CANCEL, "CRC-16" appears at the bottom of
the window, and the name of the receive folder appears.  Then the window
goes away, and I'm back to the terminal window.  The system I'm on
is running Ultrix 2.3.  Running "sz -TT" produces the following (output
was redirected):

sz: caught signal 99; exiting
mode(2) in rbsb.c not implemented!!
Please read the manual page BUGS chapter!

sz and rz were make'd with "make bsd".  I'm running a Mac Plus
with System 6.0.2, a 9600-baud datalink, 7 bits, even parity.  Can anyone
give me a clue?
