Pi>> Could someone tell me what uVAX II wants as its console terminal
 Pi>>settings?  The speed was easy to figure out as there was a knob to
 Pi>>set it to 9600 at  rear, but.. What should the databits, parity
 Pi>>and stopbits be? How about  flow control? How long time it should
 Pi>>take from power-up to get the  >>> prompt? Thank you in advance.
 Pi>9600 8N1, xon/off (software flow control).  I use a 3 wire cable
 Pi>with only transmit, receive, and ground signals going from the
 Pi>MicroVAX II console port to a VT340.
 Pi>However, the MicroVAX II DE-9 console port pinouts aren't the same
 Pi>at those used by the IBM AT DE-9 configuration which is what just
 Pi>about every pre-made cable is using these days.  I don't know the
 Pi>pinouts off the top of my head, but they should be buried in the
 Pi>archives somewhere.
