This program accepts Morse code via a logic sense line in
real-time and outputs the decoded message on the teleprinter.
The pattern recognition algorithm in the program automatically
adopts to the sending rate with the maximum reception rate of
the computer being limited by the teleprinter to about 100
words per minute. The program classifies a key down condition
as either a dot or a dash. The key up conditions are classified
either as a space in a character, a space between characters,
or a space between words. These pattern classifications permit
each character to be decoded via a table look up.
