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
