The COM port must be properly set upon program entry...

Perhaps I'm misunderstanding something (wouldn't be the first time!). The version you originally linked appears to be CONNX3 Version 2.1 Build 1330, and from what I've seen it simply doesn't support communicating with the 48 or 49 series at all.

The only thing I see with a version of 3.0r4 is the newer version of HPComm, which is available from other sources. The installer for 3.0r4 doesn't seem to work on my Win7 system (have tried with a variety of compatibility modes, with and without "Run as administrator" chosen). The included InstallShield setup.exe starts, then simply locks up before anything is ever displayed. I believe that was the original problem I had when I tried this before, which is why I had to resort to the earlier version of HPComm in the first place.

After some extended arm-twisting, I've been able to try HPComm 3.0r4 on my laptop by installing it on an "XP Mode" instance, then copying the folder it created for the app over to my native Win7 System. Though doing it this way has bypassed the usual O/S support for updating the "installed applications" data (and setting up the uninstaller), the app does at least appear to function as was originally designed. I'm pretty sure this is simply the updated version of the HPComm I already had, so I'm already familiar with its use.

Thanks for the pointer about the version you have, that was a nice clue to help see where the disconnect occurred.
