I'm using this port with a GPS and gpsd so I can turn it into a basic time server.  Gpsd itself is supposed to be able to change the port speed while it's running but it complains that it can't and the port always stays stuck at 9600.

So would this work:

 ( stty 38400 && gpsd /dev/ttyb )

Keeping everything in a single process or am I going to get stuck again?
