There was a brief bit of traffic on the net about a month ago, concernibg
the ability to toggle Numlock from software. It seems that it's quite safe
to change the state of the NumLock bit in the keyboard status byte (0:417),
though I didn't catch all the comments as our news system here is a bit
flakey.
On an XT, I believe the 'Numlock' lamp on the keyboard is controlled by
the keyboard controller directly, so if you fiddle with the status byte, the
light will not match. However, on an AT, it seems to be lit by software
action. For instance, 'Sidekick' does it when you invoke 'calculator' mode.
Can anyone tell me how to do this please? I believe you run an 'out' command
to port 61 (or 62 or 63), but I don't know the details.
Thanks in advance
Steve
