We are having problems with a communications program we wrote using COMET.BIN years ago which is integrated into our product. We currently market both a Windows version of our product and an old DOS version for existing cutomers which need more capacity. Our problem is that we can no longer detect various modem events in the DOS version running on a P4. We can dial and make a connection but after that all bets are off. I know there is a patch for 2.6 Windows but will the same patch work with DOS or is there another patch available?

Thanks
