a single bidirectional wire at 4800 bits per second. Unlike the
|

VT100 keyboard whose layout it mimics (indicator LEDs included),
|
||||
the CIT-101 keyboard transmits standard ASCII codes for most keys,
|
||||
and the complexity of decoding these strongly suggests that this
|
||||
must be done by some sort of MCU. There are also a few special
|
||||
characters with the 8th bit set, including the numeric keypad,
|
||||
the cursor keys, the Return key and the all-important no-key code.
|
||||
and a MCU is used to decode the scans, generate clicks and beeps
|
||||
and handle serial communications. The keyboard also transmits a
|
||||
few non-ASCII codes with the most significant bit set (and
|
||||
modifiers encoded in the next two bits):
