A buddy of mine's got a TI-99/4A, and I'm thinking about getting one myself. Something I'd like to do is use my old DOS computer as a terminal for it. What I'm having trouble being confident about is what type of cable to use for this. I've seen people say to use a null modem and others say to use a straight-through. I don't own any serial cables, so I'd like to get this sorted out before I spend money on something that won't work. I've got a 9-pin connector on the DOS computer side, and friend has a nanoPEB which provides a 9-pin on the TI side. I've already got terminal software for DOS, so that side is covered. What needs to be done on the TI side so that it emits terminal signals? He's got the Terminal Emulator II cartridge, but my intuition tells me that's for when you want to use the TI as a terminal, not when you want to terminal INTO the TI. I'd be pleased to be wrong, though. I scanned many FAQ pages looking for this information as well as tech docs so I could tell the baud rate to use. Basically all I've got is my intuition, but I'm a mid 90s kid so that's not worth much for 80s tech.
