[comp.sys.dec] Help on VAXstation 2000 serial

dewey@execu.UUCP (Dewey Henize) (11/04/88)

Well, having waited patiently (3 days) for our corporate contacts to help out,
I'm turning to the net.  A couple nice, simple questions.

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

What pinouts should I use?

I couldn't believe we couldn't get an answer from DEC on this!!!  Somehow I 
just cannot believe they are selling this and yet the 'support' people can't
find out! (I do believe they don't know, sadly enough)

If you get bored with this, we are also looking for the device name/MAKEDEV
parameter to use with a 8MM backup unit, but that's newer and we expect we
can at least get that from the vendor.

Thanks in advance.

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.
