loader.conf(5) says:

| comconsole_speed
|           (``9600'' or the value of the BOOT_COMCONSOLE_SPEED vari-
|           able when loader(8) was compiled).  Sets the speed of the
|           serial console.  If the previous boot loader stage speci-
|           fied that a serial console is in use then the default
|           speed is determined from the current serial port speed
|           setting.

If you specify to use a serial console via /boot.config and
want to change the speed from 9600bps (default), you need to add
the "-S speed" flag to your /boot.config.  See boot(8) for details.

Is a login prompt displayd to the video console?

If not, the system boot sequence may have been stopped at some kinds
of daemon (sshd, sendmail, etc.).
