grimjoey: I'm trying to track down the author of an application called SerialMon. If you are the one I'm looking for; SerialMon software monitoring does not seem to work in Windows 7 64-bit. And I've experienced a problem after uninstalling SerialMon in two occations. Once on a WinXP Home Premium 32-bit, and once on Win7 64-bit. The problem is that windows does not accept serial port drivers after the uninstall. The drivers flag code 39 (driver missing/broken, or dependencies missing/broken). Any idea on how to resolv this? (So far I've had to reinstall Windows).
Issue resolved by manually removing UpperFilter registry keys from Modem and Ports classes (search for hhdspmc in registry).
What's the difference?
