    You will need to keep the video card removed in order for the system to
use the serial console.

    Yes there is a manual, but it won't tell you anything that you want to
know. Your problem is most likely related to the RS-422 MMJ connection that
the PROM is expecting. Basically DEC terminals only use 6 wires to
communicate, so the hardware handshaking is done with DTR/DSR instead of
RTS/CTS because those pins are not connected (I don't think anyway, been a
long time since I've checked). Try switching to dtr/dsr or a similar
combination. I don't know what carrier-watch is, if that's sensing CD then
you do want that off as you have set it. However if that's DSR then you want
it on. That should fix it for you, my 5000/200 did the same thing to me, I
thought it was dead for about two days before I finally figured out why it
wouldn't work.
