I seem to recall that the machine side of this link used a non-standard
round connector with a bayonet locking ring instead of a DB9/DB25 so it's
not as easy as simply trying standard cables...

Machine: Vintage Boss 6 BP CNC. Accepts commands from a PC via RS-232,
rather than a tape generated program.

The CNC CAD/CAM program looks great, the post processor working perfectly,
but...........and here's the question, we need to find the pin-outs for
the
serial cable; three wires plus ground from the controller. Any input? All
is
appreciated.
