Share Serial Ports is an advanced utility for sharing real serial ports between multiple applications so that all applications will receive same data from real serial port simultaneously. It is achieved by creating virtual serial ports, exact copies of real ones. All virtual ports can send data to real serial port. You will be able to set port permissions to read, write or change control lines state for every application separately.

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.
