(Lots of stuff about writing to disk from an ISR while DOS is doing other stuff). The Microsoft Encyclopedia has a nice example program called SNAP which sits in the background and does aa print-screen type of operation to a disk file. It can do it at any time, regardless of what is happening in the foreground. By any time I mean that it will remember the request and do it as soon as things are in a safe condition. Usually less under 1/20 of a second. I wrote a TSR program for a client which monitors the serial port in this way so the activity could be analyzed later. The trick is to have multiple buffers to fill and write so you never lose any data. Ed ekalenda@cup.portal.com
