Function/Control Key Support with PortKey
The TriCoder in RS-232 ASCII mode using PortKey can emulate the
special keys on the PC keyboard. PortKey expects the "
extended key code
"
convention outlined in the BASIC manuals and most compiler manuals. For
example, to transmit a F1 key from a serial TriCoder to the keyboard, a
null
(ASCII 0) followed by a
semicolon
(ASCII 59) would be required. You can
use Full ASCII Code 39 or Code 128 to transmit the required sequences.
The following is a list of the most common keys, the required codes and the
equivalent Code 39 characters:
