Log Message:
when transmitting we cannot totally fill the circular buffer (i.e.
we can't use up all of the remaining sc->txslot[chan].bfree free
bytes) because that would cause the circular buffer read pointer
to become equal to the write pointer, thus signaling 'empty buffer'
to the hardware and stopping the transmitter.  spotted and fixed
