Description David Naylor 2008-08-30 14:10:01 UTC 
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.

How-To-Repeat: Set the following in loader.conf:
boot_multicons="YES"
boot_serial="YES"

comconsole_speed="115200"
console="comconsole,vidconsole"

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

(no output shown unless -s is omitted)
Comment 1 David Naylor 2008-08-30 14:37:38 UTC 
Apologies, in my hast to full out the PR's I forgot to change a few of the 
options.  They are:

category: kern (boot)
severity: non-critical
priority: low
Comment 2 David Naylor freebsd_committer freebsd_triage 2014-12-16 14:37:14 UTC 
Missunderstanding of how comconsole works (i.e. it does not change loader behaviour).
