FreeBSD dragonmini.dg 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Tue Aug 26 20:30:23 SAST 2008     root at dragonmini.dg:/tmp/usr/src/sys/GENERIC  i386
When using serial to interact with FreeBSD (via console="comconsole" and/or boot_multicons="YES") the connection speed is fixed at 9600 and cannot be increased via comconsole_speed="115200".  Any attempt to connect at a speed greater than 9600 results in nothing being shown.
Set the following in loader.conf:


then connect using:
# cu -l /dev/cuaU0 -s 115200

(no output shown unless -s is omitted)
