If you're talking about communicating via RS232 ports generally all you need is to make sure both computers' comm parameters (word length, parity, flow control, etc.) are compatible and set the same. Of course, both have to support some kind of file transfer protocol, even if it's a "primitive" one. Unfortunately I don't know a thing about the TRS80 desktop PCs, but computer-to-computer transfers usually require, at least, swapping pins 2 and 3; pins 4, 5, 6 and sometimes 20, 7, 8 or others can be affected, but it depends on whether you've got a 25- or 9-pin port, and also on what kind of mood the hardware designer was in!
