The heart of the package is 'libcw'. This is a library which, when built,
offers the following basic CW services to a caller program:
o Morse code character translation tables, and lookup functions
o Morse code low-level timing calculations
o A 'sidetone' generation and queueing system, using either the system sound
card, the console speaker, or both
o Optional keying control for an external device, say a transmitter, or an
oscillator
o CW character and string send routines, tied in with the character lookup
o CW receive routines, also tied in to the character lookup
o Adaptive speed tracking of received CW
o An iambic keyer, with both Curtis 8044 types A and B timing
o Straight key emulation
