	Hi!  I am working on a project which needs to connect a PUMA 560
robot and a supervisory computer.  So far, I try to use a IBM PC/XT as a
supervisor.  The PUMA that I have is a pretty old one which has a
RS-232C serial interface.  The problem that I have is when "ENABLE NETWORK"
command is issued in VAL-II, the PC can receive a "start" message according
to DDCMP format.  However, the PUMA wouldn't response after PC transmitted
a "start acknowledgement" message, i.e., no system prompt appeared on the
PUMA monitor.  I would like to know if anyone can help me, I would really
appreciate your reply.
