Regarding the BSDRP serial configuration image:
As boot block, this image uses boot0sio (boot0 with serial output) for
displaying early boot0 messages to the serial port.
This boot0 is compiled with:
BOOT_BOOT0_COMCONSOLE_SPEED=0
This allow to innerit high serial speed from the BIOS configuration,
because boot0sio code support only old slow speed
(110,150,300,600,1200,2400,4800,9600).
(cf FreeBSD sys/boot/i386/boot0/Makefile for more information about).
After the first boot stage is done, the second stage boot parameters are
declared in /boot.config.
serial-port only BSDRP image uses this parameters on the /boot.config:
-S115200 -h
-S for configuring serial speed
-h: force the serial console
After this 2 stages boot, the last stage (loader) loads /boot/loader.conf.
At this moment the system already knows it needs to use the serial port as
console and its speed.
This is why there is no need to declare a second times the serial console
values into /boot/loader.conf.
Regarding /etc/ttys:
You should no more specified console speed here (cf 2 years old FreeBSD
commit message of revisions 262957 and 267591).
1. In place of specifying speed here with old "std.38400" the keyword is
now "3wire" (and innerit from the boot/loader parameters)
2. In place of "on" the keyword should be "onifconsole", but "on" still
works great (cf 2 years old FreeBSD commit r260913).
The correct /etc/ttys should be like this:
ttyu0 "/usr/libexec/getty 3wire" vt100 onifconsole secure
Is your serial port a standard UART on your box ? (no USB, neither IPMI SoL)
