Serial modem question
Posted: Sat Feb 18, 2012 2:29 pm
is it possible to make some Sega genesis games work with a 56K Serial modem hooked up through the rear EXT serial port? kinda like the Xband but faster?
You'd have to write a new game that allowed for multiplayer via a modem, or heavily modify an existing one. You would also have to build the connector and write software to use the modem, as well as select an existing or design a new communications protocol. You can't just plug in the modem and start sending commands.
I don't know how fast the Genesis' EXT port is, but it might not be able to output data at anywhere near 56kbps. Even if it can, chances are you're not going to need anywhere near that much bandwidth. A faster modem doesn't actually push data along the lines more quickly - it just pushes more data along in the same amount of time.
First things first. Learn how to write software for a single machine before you start worrying about telecommunications... writing software that coordinates the hardware and software of two or more machines is much more difficult!
