I enabled the chat option, but still couldn't hear, or be heard during a pitboss game using the microphone. It says you need to press SCROLL-LOCK. Do you press it and hold it as you talk, or is it a toggle action thing, where you press it, talk and then press it again to finish?

I found this in another thread:
* 3783 (Voice Chat Port)
So I'll try opening that port, and see if my voice chat works. But I still would like to know about the SCROLL-LOCK operation...
