>Description:
For years I've been building my systems with a serial console running at
115200 baud.
Now, with 6.1-PRE, it seems that the console is wired to 9600 baud despite the
following settings:
make.conf:
BOOT_COMCONSOLE_SPEED=115200
kernel:
options CONSPEED=115200 # Speed for serial console
and in /etc/ttys:
ttyd0 "/usr/libexec/getty std.115200" dialup on secure
/boot.config has "-Dh"
The serial port insists on running at 9600 baud during boot/shutdown and even
getty has its speed overridden to 9600 baud so login is at the slower speed
too.
>How-To-Repeat:
upgrade 5.4 system to 6.1-PRE via source with above settings. serial console
insists on being 9600 baud.
>Fix:
I wish I knew. It works as expected with the above settings since version 4.1
through version 6.0-REL-p4.
