  Hmm, I'll have to check that again.  I recently changed JR-Comm to use the
buffer size in Preferences rather than forcing it to an 8k size.  I forget
when I did the XON/XOFF tests though, before or after.  If it was after, then
the buffer size was 2k.

  If the device does indeed work as a percentage of the buffer size, that's
better, but using the baud rate in the calulation would be best, agreed?
