[gpsd-users] Baud rate of 230400

[Tomalak Geret'kal]

Guys

I've done a fair bit of gpsd hacking in the past, adding 
support for proprietary NMEA sentences and the like. Nothing 
that warrants pushing to the actual repository, and I'd 
still be nervous doing that anyway.

Anyway, today I needed to point gpsd at a receiver that 
requires 230400 baud because of the sheer quantity of 
additional data it's pumping out. Alas, 3.4 can only 
auto-detect up to 115200, and passing the `-b` flag doesn't 
appear to stop it from doing this.

I find that I can modify serial.c to add support for 230400 
baud (gpsd_get_speed and gpsd_set_speed) and things seem to 
work; our termios.h(3) *does* have the constant B230400. 
Also, files like fake.py already seem to support it.

My question is whether there's a reason gpsd only goes up to 
115200. Is termios.h's support of B230400 not as commonplace 
as I thought? Would a patch for adding 230400 baud support 
be welcomed?

Regards
Tom
