I was very concerned when I first got the cable that something was wrong--even with HyperTerminal I was losing faith with XModem until I tried the IOMan version (I was getting text to appear properly on the screen, so I knew the cable HAD to be working in some capacity). But, for Conn4x, I get the exact results Jim D. does--nothing at 9600 baud of lower using XModem Server.

Thanks for the lead. If it's a kit, though, it may be the same type of thing they sell at Fry's. It was in a blister pack containing a cable and several adapters. One of them looked like it would fit, which was called a flat 4 USB adapter. At that point I didn't want to spend $30 just for an adapter, when I really needed a cable with that connector on at least one end. Norvac had some surplus cables with a USB type A connector on one end, and pig tail leads on the other. I was thinking about using that for connecting to a minibox which would house the RS-232 circuit hardware. From the USB type A I could then adapt to just about anything on an as needed basis. Some of the equipment I want to use this with has RJ-45, DB-9M, and DB-25M connectors. -Dot-

I haven't checked it rigorously, but it seems to work on my system with Conn4x and XModem Server. The USB side works just fine. Makes me wonder what the problem is with some of the other baud rates. Maybe serial communications was actually designed to be used as a torture technique to drive people crazy? (It's working!) -Dot-

Standard in the box.
