Map Serial Ports
Serial Port Mapper is a tool that maps COM ports to any port number. The program allows legacy applications to transfer data over any serial port even if it is not accessible for the application.
If a legacy application is designed to work only over COM1-COM4 you can use Serial Port Mapper to assign the alias for available serial ports with different names.
Assign alias to any COM port
The program allows mapping any serial port to any new port name.
Swap COM ports
Serial Port Mapper allows swapping serial ports. In other words, it allows to exchange names of two COM-ports.
Port aliases look exactly as physical COM ports
Serial communications program opens COM port alias but actually works with specified physical COM port.
Command-line control support
Additional console utility allows controlling Serial Port Mapper via command-line interface.
