# What is the device name of the serial port on a 2000 running Ultrix?

# What pinouts should I use?

Device name?  The driver is called se(4) -- most of the device drivers on the
2000 are s?(4), where s = "small" and ? = {e(thernet),s(erial),dc(disk ctrlr),
g(cfb),m(mfb),tc(tape ctrlr)}.

Reading the man page for ss(4) helps a lot, though it doesn't have the pinouts.
I think one of the ports back there is a 25-pin, which will be RS232C DTE (so
you could connect it to a modem with a flat ribbon cable that crossed no wires
but you'd need to use a null modem cable for a terminal).  The others, I don't
know -- ohm out the DEC cable, I guess.
