I have two computers linked together(Both on COM1), using a serial link. And I am using bioscom(), in bios.h to send bytes across, I initsialize them both with the same settings, but i can only send from one computer. I can send a byte on one which will get picked up by the other, but i cant do it the other way around. I have run quake multiplayer, and that works so i don't think it is a broken cable. (The communication had worked previously). can someone write me a small program that will send and receive single bytes, just so i can compare what i am doing to see if ne thing is wrong. thanks
