Port Mapper is a freeware tool which manages ports on your home router/gateway to enable online multiplayer game play. It can also be used to expose applications to your friends over the internet. If you are a gaming freak who loves gaming on the internet and don't want to be disturbed with the manual opening and closing of ports at your router, you are sure gonna love this tiny tool.

Serial Port Mapper allows you to map any serial ports to any other serial ports. For example you install additional serial port expansion card to computer as COM7 serial port but your favorite software can work with COM1...COM4 ports only. To resolve this problem you can use Serial Port Mapper to map new COM7 port either to COM1 or to COM2...COM4. Now your software can open COM1 port (or COM2...COM4) but actually work with new COM7 port.

This is a very simple command-line port mapper (port redirector). The program is able to work in the hidden mode.
