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 B ASIC manuals and most compiler manuals. For example, to transmit a F1 key from a serial

TriCoder to the keyboard, a n ull (ASCII 0) followed by a semicolon (ASCII 59) would be req uired. You can use Full ASCII Cod e 39

or Code 12 8 to transmit the required sequences. The following is a list of t he most common keys, the required codes and the

equivalent Code 39 characters:
