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

[Graham Gower]

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?

Have you upgraded firmware to the latest version (I think it was 3.8)?
Sometimes it helps to flash again and reset all settings to factory
default.

Have you actually redirected SRM to the serial port by "set console
serial"?

I'm unsure of how to do this without a floppy drive. But yes, I have an
older firmware version (3.5-72).

Is there a manual for SRM somewhere that I should know about?
I just tried this and bad things happened.

Ok, the panic was actually caused by the network cable being unplugged during
dhcp (!!!).

In any event, 'set console serial' gives no different behaviour to before.
