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:

PC Key		ASCII Character	Code 39
Ctrl @	0,3		%U$C
Ctrl A	2 (SOH)		$A
Ctrl B	3 (STX)		$B
Ctrl C	4 (ETX)		$C
Ctrl D	5 (EOT)		$D
Ctrl E – Ctrl Y	6 (ENQ) – 25 (EM)		$E - $Y
Ctrl Z	26 (SUB)		$Z
Ctrl [	27 (ESC)		%A
Ctrl \	28 (FS)		%B
Ctrl ]	29 (GS)		%C
Ctrl ^	30 (RS)		%D
Ctrl _	31 (US)		%E
