Why not get into DOS? Its not difficult to learn and it will save you time in the future instead of having to ask other people questions you can find out for yourself.
Ill teach you how to find out the port number of any server you connect to.
Open a DOS prompt, type in: netstat
look at the output and decipher it.
It shouldn't be too hard to figure out which connection is the quake server if you know the server name or IP it will be even easier. Apply process of elimination techniques and shut down all other connections that you have and it should be the only one there. If you know the IP of the host use: netstat -n, it will give you numerical output. For more assistance using netstat type: netstat -?
Learn how to learn and teach youself, it will help you more than we ever can.
