Problems connecting to GPS

Hello friends,

I am trying to get my trimble sq to talk to gpsd.  On my laptop, the
trimble is embedded and connected to a Oxford Semiconductor Ltd
OX16PCI952.  According to some sources, there is a bug with this
hardware where the baud rate cannot be set directly.  With the speed
set to 921600, data come from the trimble once a second, but when I
connect with gpsd, it tries to connect at 4800, then 9600 and fails
after a couple minutes with the message "cannot sync up", then closes
the port.

So, maybe a quick solution would be to set the baud rate without
letting gpsd guess it, but i can't find an option anywhere to do this.

any ideas?

GPSD autodetects port speed at runtime. If you're sure that you only
need a single speed, you can build a copy of gpsd to do this - there
is a configure flag for that: --enabled-fixed-port-speed=#####

GDB has a 'break' feature; why doesn't it have 'fix' too?

Since it's a Trimble, maybe you need the patch that sets up odd parity
for the Trimble probe that Chris recently sent to this mailing list.  
The patch worked for me after I applied the fix that I forwarded to Chris.
