[amsat-bb] SatPC32 Ver12.8c and CAT Operating

[Tom schuessler]

Yes Alan,  it definitely is an issue at the 57K baud rate but still is at times at 9600.  And you would thank that a USB to serial adapter would work happily at 9600.   The only way to be portable for me is with a USB only laptop.   I do currently have the cat delay set to 30 but I can try with some different numbers.
