Re: [bluetooth-dev] [PATCH] Brainbox 620 Pcmcia card at 921600 baud
I don't know if it will work for you, but I added support to OpenBT
to specifiy the baudrate as "baudbase/divisor" that will use the
SETSERIAL ioctl() to specify baudbase and custom _divisor.
In theory you shouldn't need setserial but I guess it only works if
the driver knows how to change to the correct baudbase...
