Anybody know anthing about hercules graphics?

I'm trying to do some graphics programming with my AT clone - but nothing
seems to work. The BIOS doesn't respond to set-mode and set-pixel calls BUT
programs written for hercules work perfectly.

I have started disassembling some games programs that directly fire
commands at the hercules OUT port, but this is rather difficult since often
the screen goes crazy and I have to reboot the system.

Has anybody got a list of what the different commands to the hercules port
mean?

Many thanks
