Implements everything from talking directly to the chip, through a DTMF_OUT buffer that is handled by interrupts in a multitasking system. (This functionality depends on some basic buffer management functions that are not included in this package See 'Getting Started')
The dialer implements an algorithm to speed up the DTMF dialing by reducing the silent time between dis-similar digits.
This may be useful to Picsters too, since the basic logic is all you need.
