So, I'm working on a standalone PS/2 keyboard driver for the 83PBE, partly because I want one and partly because I need a project to work on. So, I decided it would be a lot easier if I could use the link port interrupt. However, I haven't been able to figure out what sort of link port events trigger this interrupt. Anyone know?
You could use a hook, but trust me, I've tried, and it's too slow to catch. Just use a regular interrupt that polls the interrupt. I've been working on a similar project with Ben Ryves' Emerson routines.

I think you mean that polls the port.
But I found that the link interrupt is triggered when either line is pulled low, so I can use the interrupt that's triggered to check the data line. (Yes, I'm disabling on and timer interrupts)
On a slight side note, I was thinking of a silent link hook that could try to see if the connected device is a calc or computer. If not, cancel the silent link. This would eliminate freezes when plugging in speakers and such. Whaddaya think?
Not a bad idea, but the sheer frequency with which it would get triggered (ie CONSTANTLY) would probably ruin the point.
