Sounds like the simplest of basic RS-232 cables. I've pulled my hair out over
serial cables just as simple, until I ran across the sure-fire solution that
works everytime, connecting any two serial devices: SmartCable
They use a small logic chip. Just connect it, with adapters if neccessary,
and try some output with the slide switch in one of the 3 postitions. One will
always work.
