Serial Woes.

swestrupSo, I haven't been able to get the serial IR receiver working on my PVR. It could be any one of a whole host of problems, and I'm trying to narrow things down. First off, I need to know that I'm A) programming the correct serial port (this machine has two, and I don't know which is which) and B) that the serial port I'm using actually works.
My plan was simple: I have an old external 2400-baud modem with auto-adaption capabilities so that if a serial port is even vaguely usable, I can talk to the modem and it can tell me what is up with the port. All I need is to connect it to the machine with an appropriate serial cable, and I'm good to go.
Well, that's my next problem. It seems that I no longer own a serial cable with a male 25-pin end on it. I do have some 25-pin to 9-pin adapters but they're all female-25 to male-9 where I need male-25 to male/female-9 to get things to work. With all the cables and adapters I have this should have been easy to come up with, but I'm surprised to find myself missing crucial bits.
So, before I go out and buy a serial cable adapter that I will only be using for a short time for diagnostic purposes, I thought that I would ask my friends list. So, does anyone have any old serial cables or adapters around that I could use to hook an old serial 25-pin DCE device (modem with female 25-pin connector) to a modern DTE (computer with 9-pin male connector) that I could borrow?
