Seems like there should be a command to change the baud rate.
I've always just edited the _pmtab file.

disable the port (assuming pmadm -l shows it enabled)
# pmadm -d -p zsmon -s ttyc

change the baud rate to what you want
# vi /etc/saf/zsmon/_pmtab

Enable the port
# pmadm -e -p zsmon -s ttyc

Sometimes you need to restart the port monitor. (will effect all ports on zsmon)

# sacadm -k -p zsmon

# sacadm -s -p zsmon
