I've always wanted to build a digital thermometer to interface with my
computer. When I was using DOS, I thought it would be a fairly
straightforward task of direct hardware manipulation to gather the
information from the device.  With OS/2, I'm not so sure.  Because of the
greater protection OS/2 affords the entire system, will I be required to
write a device driver to access the CPU ring that allows direct port
manipulation?  Additionally, can someone provide some information, perhaps
direct experience, on the matter? Any help would be appreciated.  Thanks.
