DEC Multia VX40 - missing login on serial port, shutdown strangeness

Hello list,

I recently acquired an old DEC Multia VX40. No floppy, no cdrom, broken
netboot, cpu heatsink works for frying eggs. Installation via
$ dd if=floppy44.fs of=/dev/rsd0c
from another machine worked a treat and now I have a working system.

However, I cannot figure out how to get a login prompt on the serial
port. If I boot the system without keyboard/monitor attached, then the
SRM console appears on the serial port and kernel messages also get
through. In order to do the installation I had to attach a keyboard and
monitor - at the end of the installation I said yes to console on com0.

I've tried adding various lines in /etc/ttys with no avail. I can get
a login on the monitor using ttyC0, but no luck with ttyB0 or tty00.

Now, if I login via the keyboard/monitor, I can type 'halt' and get
back to the SRM console. However reboot and shutdown fail to do either.
They tell me about /etc/rc.shutdown being run and then finishing, but
then hang. A ^C sometimes gets me back to the shell.

With the keyboard unplugged and a serial cable attached, no combination
of halt/reboot/shutdown gets me a power down or SRM console on the
serial port.

Anyone still running OpenBSD on a multia? I see some messages in the
archives regarding PCMCIA - did anyone ever get this going?

-Graham
