Output Hex Keyword

<OutputHex H>
<ox H>

    O switch alternative that outputs data to the currently installed output port.  Item file must have selected <InputDevice PIO12> or some other device that supports output.  O outputs the word N1 or the value of counter N2 (at item parsing time) to the current output device.  If the <RevertOutput> parameter hasn't been used the PIO12 output's will stay latched with that output until either another O switch is encountered or the item file is stopped (in which case the lines all float high which is usually seen by other devices as all 1s).   The variant accepts hexadecimal codes instead of decimal codes, handy for the multi-byte output devices below.

    If the input device PIO12 has been installed then 8 bits of output are provided on port C of the PIO 12 (ports A and B are 16 bits of input). If the PIO12output16 device has been installed 16 bits are output, the lower 8 to port C and the upper 8 to port B (port A is 8 bits of input). If the PIO12output24 device has been installed 24 bits are output, the lower 8 to port C and the middle 8 to port B and the upper 8 to port A (no input bits).

    The counters variants are evaluated at parse time so sequences like the following where data is to be sent to port B instead of port C (when counter 2 is 256) are fine:

<set c1=c2*255><op c1> / <set c1=c2*123><op c1> / <set c1=c2*255><op c1>
