I added tests to the combined test suite for the Input instruction and the telephone dial input facility.

So that dial input could be tested automatically, I added a trigger circuit that watches the teletype output looking for the sequence of characters D#n, where n is a digit, and dials that digit.

Changes to main circuit

Dial test trigger subcircuit

Changes to dial simulator subcircuit

Additions to test program for input testing

#   INPUT instruction
#   Enter with AC = 0
