I would like my startup script to cat messages to ttyS1, as well as to 
the console (ttyS0). Basically for the purpose of informing users that 
the firmware cannot execute for some reason (we don't like to give 
access to the console). I was trying to avoid including stty or 
setserial, but if this is the accepted way to configure the serial port 
it's not a big deal ;-)

Interesting...I also tried manually entering a value here, but it 
didn't seem to have any effect. Maybe it just isn't used?
