To find DEC MMJ cables, go to
http://catalog.blackbox.com/BlackBox/templates/blackbox/search.asp
and look for keywords DEC MMJ.
You will probably need at male-male MMJ and a female MMJ to DB9/DB25.
AS with any serial connection, verify pins (on a DB-25) 2-7 and 3-7 (i.e.,
make sure terminal/PC is transmitting on one line, DEC VAX is transmitting on
the other). I usually do this with a VOM; transmit will be a strong (5-15
VDC) signal; receive may be around 0.
Usually you will get a >>> prompt from VAX firmware. It will accept a help
command and you can do "show devices", then try "boot dua0:" or some other
disk device that's listed (they are 99% devices beginning with "d").
Of course you may get a very first product/CPU ID, then some testing
messages. You are hoping that it progresses through the self-tests and gets
you to the >>> firmware prompt. Often >>> will take a "help" command too.
Often you need to send "delete" and not "backspace." Try 9600/8/N/1 settings.
Also probe the Compaq, Montagar, and Process sites. With the VMS hobbyist
program you can get going pretty well these days.
