[comp.sys.atari.st] IO port bits...

Jonathan Nagy wished to be informed what events are represented by I/O
Port bits 0-7 listed in the MFP 68901 chip interupts...



bit #        function
0            Centronics busy
1            RS-232 data carrier detect
2            RS-232 clear to send
3            reserved(not used)
4            keyboard and Midi interrupt
5            FDC and HDC interrupt
6            RS-232 ring indicator
7            Monochrome monitor detect
 

  If you need further help in implementing any of these interupts let me know
via e-mail, and I'll help as much as possible.
(I posted this to the net instead of a email due to the fact that it is
something that stumped me for quite awhile, and I hope to save others the 
hassle of finding it!)
