Head scratching, but hey its Friday!

I have a programming PC connected to a master control via a 3 wire RS-232 cable connection. In my never ending desire to clean up my COMM room, I got some 2 pair Cat 3 cable, 2 connectors, and soldered up the connection. Plug it in and NO WORK.

I recheck my pins, wire colors, all OK

I have a co worker double check me, all OK

Then I check for bad joints, wire continuity, and even made a second cable. NO WORK.

So I walked away....screw it, its Friday!

Ever have stuff like this? It SHOULD work, wired exactly the same as the other, only 5 feet longer, total of 18 ft. Geez

And Im out of coffee...

Maybe that's exactly the problem, it's 5 feet longer ! Maybe your serial port is not strong enough to send the data through. Just for fun, make a third cable "from the same spool" but at 13 ft and see if it works.
