Fix for SSC (big transfers): use queue instead of single byte buffer New switches: -log, -no-mb, -spkr-max, -spkr-inc Fix for Speaker underflow problem (max=200, inc=20) SSC: Support 112.5K Baud Dynamic 'Serial Port' drop-down menu Save "Serial Port Name" to Registry (instead of drop-down menu index as "Serial Port")
