Do you own / know how to handle a soldering iron? If
yes, search the net
for the wiring of a VAXstation MMJ serial console cable. It is the
same. You may find a link to the MMJ cable wiring on this page:
http://anacin.nsc.vcu.edu/~jim/mvax/mvax_faq.html
It is easy to build a MMJ cable from a regular phone cable. Cut off the
tab of the RJ plug and solder a DB25 at the other side of the phone
cable.
Ok, I got ahold of a 6-prong telephone cable, clipped the tab, and
soldered connected it to a DB25 cable using the following pinout:
Wire# Signal Color Destination/25pin plug
1 DTR White 20
2 TXD Black 2
3 GND Red 7
4 Com Green 8
5 RXD Yellow 3
6 DSR Blue 6
Still, I can get absolutely nothing to display on the terminal. My
solder job is horrible, but I don't believe so bad as complete stop the
connection. I've tried booting the system with the S3 switch in both
places and with and without a null modem adapter in place (do I need one?).
Any suggestions as to what I should try next?
Thanks,
Tom
