I have some Hayes ISA modems and they loved to do this... The problem was well documented in the original manual and/or the small update sheets that came with it. Do you have them? (I could look for mine later.) I remember it was a hassle getting the things installed, but once in they are still running 7 years later. Which model and type do you have?

I thought there were only 4 COM's 1 thru 4. If I want some other s/w to use the Modem, it is not detected as it searches 1 to 4 and reports Modem not found. How do you have Com 5 and how do I get over my problem? The NOSPIN Group is now offering Free PC Tech support at our newest website: http://freepctech.com
