I have bought a “modern” serial cable, with 2 10 pin IDC connectors and 2 DB9 ports. The idea is to connect it to my recently acquired 486 motherboard, a 486-GIO-VT.
Now I just learned that there is no definitive standard for these things and that the pin layout on the motherboard headers might not match the cable. Even worse, I might be able to destroy my motherboard in the process of trying.
Is this true? How big is the risk that I fry my motherboard?
