Hi,
I'm having issues connecting Garmin GPS 18 to COM1 on 9.1, I get
nothing but silence. Identical setup works absolutely fine with Linux.
I've got PPS wire connected to DCD, but that seems to make no
difference on Linux, so I presume it shouldn't affect fbsd either.
On Linux, I get:

With FreeBSD, the story is different:

# cu -l /dev/cuau0 -s 4800
Connected
and after the 'Connected' there is just silence (should be getting
$GPGLL every 200ms from the GPS unit)...
Obviously I'm missing something, just can't figure out what it is...
Cheers,
