Subject: MicroVAX I console port question.

Off-topic, but maybe somewhat related to MicroPDP-11's... I've got a
MicroVAX I in a BA23 enclosure. I'm presently a bit thrown by the serial
console port. I'm used to the 9pin MicroVAX II ports. From what I've
been told, the DB25-M connector for the console requires a special serial
cable for connecting the MicroVAX I up to a terminal. A null modem cable
is not adequate.
First, I just wanted to verify that this is correct. So far I haven't
been able to access a console prompt using either a null modem cable, or a
straight through cable. So either the system isn't working correctly, or
I need to get the cable right. Secondly, if it does require a special
cable, then what are the pinouts for that cable?
I'm guessing that aside from the processor itself, the MicroVAX I is
probably a lot closer in design to its contemporary MicroPDP-11 systems.
So I'm hoping that the 25pin console port is simillar to what some of you
have worked with on your Q-bus PDP-11's.
