The audio/morseplayer port
morseplayer-1.4p1 – morse player
The morseplayer utility reads from its standard input and plays
corresponding morse code sounds from an audio device. The program has
the full character set for the ARRL/FCC Element 2 examination, and
generates the timing of `dits', `dahs', intra-element spacing,
character spacing, and word spacing as specified by the ARRL.
