John's suggestion works for me with a bunch of DELL's servers (1950,
2950 and R710). I can activate the SOL (Serial Over Lan) easily. I only
need to tell the loader to set the console flag for UART1 (I did it via
device.hints instead of using loader.conf, mergemaster complains every
time, I'll move that setting in the next update cycle).
I
I also needed to tell the DELL BMC (in its BIOS) to use UART1 and to
redirect the UART1 (which has no physical connector) to the UART0. I
guess you need to tweak something in the BIOS.
I'd say I know someone also doing this with an few old supermicros,
but I'm sure they run FreeBSD or Linux. I can check next monday.
OTOH, setting the comconsole speed to something higher than 9600 has
never worked for me, neither with the DELL servers nor with any other
FreeBSD box without SOL. The handbook states that the "comconsole_speed"
sets the console speed, but John says "console_speed" is the parameter.
Is the handbook outdated?
