The maximum speed I was able to use PCMaster was 38400, but in this case the 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.
