MorseCode() — Plays Morse code
Plays the string, encoded in
International Morse Code. The following channel variables will affect
the playback:
MORSEDITLEN
The length, in milliseconds, of a DIT. Defaults to 80 ms.
All of the other tone and silence lengths are defined in the International Morse Code standard with respect to the length of a DIT, and therefore, each of the other lengths will be adjusted suitably.
MORSETONE
The tone, in Hertz (Hz), which will be used. Defaults to 800 Hz.
