GrandFather,

I feel soooo stupid. I happened to already have one of these in my "shelfware" box, but I didn't realize it.

About a year ago, I ordered an RS-232->RS-485 converter from Omega Engineering and they sent me a USB->RS-232 converter by mistake. I offered to send the wrong one back, and they said "Aww, just toss it", so I tossed it in my shelfware box, and then totally forgot about it.

Subsequent to my posting, I started thinking "What was that wrong thing?", and dug through the shelfware box. Sure 'enuf...

Works as advertised - running the device's "Install" program makes it becomes a COM port, and Win32::SerialPort talks to it just fine.

NOTES:

The device becomes a different COM ports on different computers (e.g. COM6, COM11).

This particular imported no-name USB->RS-232 device was based on the Prolific (a Taiwanese company) PL-2303 chips, as I suspect many commercially available models are. Use the install software that comes with the device - NOT a generic driver from Prolific. Make sure the device says it supports Windows 7 if that's what you're going to use it on. I installed it successfully on one XP computer using the device manufacurer's software. When I tried in on another XP computer using Prolific's generic sofware from their website - it failed miserably. Reboot after installing -even if it doesn't tell you to do so.

Sorry to bother everone with this question,

Dave
