tt2text converts a Touch Tone squence to text. There are two types of encoding:
Multi-Press - Used for comments.
Letters are represented by one or more presses of the same key depending on their order listed on the button. e.g. Press 5 key once for J, twice for K, thrice for L.
To specify a digit use the number of letters listed on the button plus one. e.g. Press 5 key four times to get digit 5. When two characters in a row use the same key, use the "A" key as a separator.
Two-Key - Used for callsigns.
Digits are represented by a single key press.
Letters (or space) are represented by the corresponding key followed by A, B, C, or D depending on the order of the letter in the order listed.
