The maximum speed I was able to use PCMaster was 38400, but in this case
routine was called every 300 microseconds. Alternatively you can make it
interrupt-driven but don't expect too much speed increase because it's pretty
tough to process commands and assemble the packets on that speed. I use it
stable 19200 bps.

> Betreff: [motoroladsp] PCMaster Baud rate > I want to up the PCMaster Baud rate from 9600 as it has been
> I have found the Baud rate configuration in pmasterdrv.c in the BSP

> Does anyone know why it doesn't work at anything other than 9600,
