Is there a way I can check if a channel is open on another computer. Basically is there a way I can check if a computer opened a channel on port x from another computer, wirelessly?

Sure, you can write a program to ask the other computer if it has a given channel open, and write a program that responds to requests for information about open channels. There's no built-in way to do it, you'd have to code one.
