|
||||
Visual 102 keyboard emulation (somewhat preliminary).
|
||||
|
||||
The internals of this VT102 lookalike seem typical of Keytronic keyboards. It transmits ASCII codes and receives commands at 600
|
||||
baud (8 data bits, no parity). The Visual 220 keyboard is different but apparently uses the same protocol.
|
||||
|
||||
The input port definitions use the standard U.S./U.K. keyboard layout, though three alternate European layouts can be selected
|
||||
through software commands.
