Does anyone know what else I may be missing to use uart(4)?
As Andrew pointed put, you need to update /etc/ttys as well.
Also, we have some boot scripts locally that will try to set
machdep.conspeed based on hardware type; uart(4) doesn't seem to
expose
a sysctl by that name. How does the uart driver for stable/7 deal
with
differing console speeds?
uart(4) has 2 approaches for this:
1) you don't specify a speed -- in this case uart(4) will
simply re-use the speed that hardware is programmed for.
2) You do specify a speed - uart(4) will reprogram the
the console speed based on the hw.uart.console tunable.
Note that for compatibility with sio(4) hints can be
used as well. Use hint.uart.0.baud=9600 to set the
console speed to 9600 baud.
There's no compiled-in console speed. The compiled-in default
(in a way) is to use the speed the hardware is programmed for.
