Change communication parameter to work better with FTDI

Browse Source 
The parameters used with the FTDI USB serial port drivers didn't work
well with directly with libftdi1. The new baud rate results in the same
effective baud rates for both.

The rbstream block size was reduced to help with the unreliability of
the libftdi communications.
