Hello, This week I finally got the DPMI specifications from Intel. It took me 3 month to get it and I had to pay *$80* for the express-service. That is NOT what I call "at no charge". My question is this: I ordered the spec's (Number 240763-001) AND - Programming examples - Test suite. I seem not to have gotten these last two. Can anyone tell me what these are and are they usefull? I have got the feeling I can't do much with what I got until now: I want to write an interrupt driven IEEE-interface under windows (DDL?) and write the userinterface with Actor. Because DPMI is not documented in the Microsoft-literature I ordered the DPMI- specifations. Bart Smith.

I hope you have a lot of time and a good hold on sanity, because, Brother, YOU ARE GOING TO NEED IT :-) The DPMI is only partially supported under Windows3. If you are going to be running in 386 enhanced mode and are looking for fast interrupt response, you probably also need the 10 interesting pages out of the DDK documentation. But $xxx dollars is a lot for 10 pages. The easiest way is probabaly to write all your buffer management and interrupt handling as a TSR that is loaded before windows. Then do your IO checking via a polling interface out of the windows VM. If you want to notify your windows program of events in _nearly_ real time then down load one of the public domain DOS interrupt lists and look at the new spec for the windows bit of int 2F. Good Luck. -- roger@bj.co.uk (UK only) roger@boldon-james-limited.co.uk (Internet) ..!mcsun!ukc!pyrltd!bjcong!roger
