Shared Serial Ports is an advanced utility, the purpose of which is to share real serial ports between multiple applications in the way, that all applications will receive same data from real serial port simultaneously. It can be used for serial port emulation, as it connects real serial ports by creating virtual serial ports, which are same copies as real ones. Each application will think that it is working with serial port in exclusive mode. All virtual serial ports will be able to send data to real serial port. Also, you will be able to set permissions to read, write or change control lines state for every application separately.
