the wave presented on the cassette port. The result is the
number of 29 t-state cycles required to find the end of the
wave. The byte at FF8EH determines if the count will trigger
on a high or low pulse. For example, a 1200 hz signal, which
would take 416 ms to go through half of the wave, would cause
this routine to exit with a value around 35. If the sound
option is turned on (see FF44H), this routine will click the
beeper on each call. Note: Although this routine analyses
the cassette port in 29 T-state intervals, the actual routine
