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. -brian. --- Brian "JARAI" Chase | http://world.std.com/~bdc/ | VAXZilla LIVES!!!
