Notes

Most DOS applications support only COM1 through COM4 serial ports. The change port command maps a serial port to a different port number, allowing applications that do not support high-numbered COM ports to access the serial port.

Remapping works only for the current session and is not retained if you log off from a session and then log on again.

Examples
    change port com12=com1

Errorlevels

none.
