Which are..... $1000/16 port console last time I looked, plus 
ridiculously expensive specialized cabling with pinouts invented by Bozo 
the wiring clown, doesn't necessarily work at all given the extremely 
poor BIOS testing of new motherboards and failure to test "remote 
console", and notice what I just said about resetting the BIOS if it 
fails to reboot 3 times in a row?  That usually disables the so-called 
"remote console" or actually the serial BIOS access. So does any update 
of the BIOS itself, even if it's for a critical repair.
Serial console is most reliable for system shell access, not BIOS 
access, due to these little adventures. It's OK if you retain keyboard 
and console access for such emergencies, but it's not a complete 
solution to the BIOS management problem.
