I've only know of Apple's in-house built twinax card. I've only seen it ONCE and apparently they DID sell them but they were obviously not a hot seller.
I'm pretty sure one of IBM's twinax cables for their own cards and terminals will work fine with that card but if it isn't the Apple card I have no idea where you could find extensions.

That sounds like a description I once read of the difference between RS-232 and current loop. "They are very similar but totally different" :D

yeah that sounds about right. you can convert rs232 <-> 20mA with a simple circuit that uses optoisolators and emitter followers.
