Map serial ports to any other port names, swap existing serial ports.


Serial Port Mapper allows you to map a hardware COM port to any new port name. The application creates aliases for COM ports and redirects the necessary data.

Some serial communications applications work with hard-coded COM port names only (usually COM1-COM2). Such applications cannot access other COM ports. In case when you want a communications application to work over other COM ports, Serial Port Mapper solves this issue.

How it works

Serial Port Mapper maps existing physical COM ports to any aliases you need. As soon as the program assigns a new name to the selected physical COM port (for instance a COM1 alias is assigned to existing COM8 serial port), a communications application becomes capable to open necessary physical COM port over a new assigned name. The COM port which has been unavailable for communications applications now becomes available and suitable for work.

Assigning an alias

Assigning an alias

Serial Port Mapper allows you to map any COM port name to any necessary alias.

True COM port emulation

True COM port emulation

The program fully emulates internals of mapped COM ports. Serial applications open the COM port with a new alias but the actual work is performed with a specified hardware COM port.

Command line control support

Command line control support

Serial Port Mapper supports command line interface. It allows you to configure the program without using GUI.

Works as system service

Works as system service

Serial Port Mapper makes serial ports aliases accessible at every system start up prior to user's logon. You don't have to adjust anything, everything is ready for work whenever you need it.

Usage example

Serial Port Mapper

There is no serial ports on your computer. To connect a serial device a USB-to-Serial adapter has to be used. The adapter is accepted by Windows as COM5. Your serial communications application can access COM ports with number COM1-COM4 only. It means that the communications application can not open COM5.

With the help of Serial Port Mapper you map the physical COM5 to a COM3 alias. Now the communications application can open the physical COM5 port over the COM3 alias.

OEM License Benefits

OEM License

Serial Port Mapper is available as OEM. The program can be integrated into your software. Developer API allows configuring and controlling Serial Port Mapper in your software.
