Keyboard Sensing Passive/Modifier Keys...ALT, Shift, CTRL..etc

CassLan

Has anyone had any experience sensing the state of these·Modifier Keys by themselves with any of the KB Drivers for the Prop?
The question comes up for me as I'm trying to sense the state of the ALT key to trigger a Menu.

I did a project way back when and had studied the PS2 protocol a bit, I know its in there, but not sure if that ability is in any of the public KB drivers.

I have been using a seperate KB and Mouse Driver, and I should probably switch over to the combo driver just as not to waste a cog.

Any ideas or help in this matter is much appreciated.

Rick

I have hacked the original Keyboard driver a bit, so that it sends now a $F4 for Left-Alt pressed and $F6 for released.
I have not invested a lot of time, so there is perhaps a nicer solution than this little hack.

Look in the Assembly section where the '////// comments are for the 3 modified lines.

Whoever designed the PC keyboard was ... uh ... "best-heard".
Well I guess IBM never liked ASCII or ANSI or EarthText.
Their mainframe text format is Extended Binary Coded Decimal Information Code (EBCDIC).

VIRAND, If you spent as much time SPINNING as you do Trolling the Forums,
