Why do I need SerialRemap ?

There is an endless variety or reasons why you may need remapped serial ports created in your system.

For example, here is a COM9 port in your system, but your application only support from COM1 to COM4. Now, you can use SerialRemap to create a virtual serial port named COM3, which you may use instead of COM9. All data sent to COM9 port would be received by COM3 port. SUDT SerialNull can create any number of pure virtual serial ports in your system connected into pairs via virtual null-modem cable without having real serial ports occupied.
