RE: A85: Re: ON key and TSRs in Usgard
The ON key doesn't go to the GetKey buffer. It uses a different port than
the rest of the keyboard. I just wanted to know whether TSRs installed with
Usgard get called when the ON key is pressed, or if they only respond to
the 200-times-per-second interrupts.

Yeah but i think you have to clear the getkey after so the TI-OS doesnt
call an error break.
