Microvax 3100/90 OPA0

My "new" Microvax 3100/90 has 4 serial ports, 3 MMJ's and one DB25-M. The
MMJ's are numbered 0, 1, and 3, and the DB25-M is labeled 2. I assume the
one labeled 0 is the console OPA0 port. There is a big yellow sticker above
the ports that says "0 OPA0" but it has a big arrow pointing to the RIGHT.
(the ports are numbered 0, 1, 3, 2 from left to right). This sticker seems
to be really odd.

My MMJ cable should arrive Tuesday. I'm planning to connect to my PC serial
port and use a terminal emulator to control the console. I assume I need a
null-modem/crossover cable to go from my PC COM port to the MMJ jack...
Correct me if I'm wrong.

Does anyone know if it is possible to use the DB25-M port as OPA0 instead,
like you can on the VAXstations? My MMJ will be here on Tuesday, but if I
could use the DB25-M, I could get my machine up and running this weekend :)
