Shared Serial Ports
Share real COM ports between applications

Share 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, that are the copies of the real ones. Each application will think that it is working with serial port in exclusive mode. All virtual serial ports will 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. Shared Serial Ports is a simple, low-cost, and efficient solution to share one serial port among multiple applications at the same time.

Common objectives and our solutions

One port for multiple applications

Shared Serial Ports creates any number of virtual copies of a real COM1, that serve as common physical ports to all applications and ensure the integrity of data transmitted from a serial device to all applications. For instance, GPS device receives information about location of an object. GPS device sends this data via a serial port (COM1) to a computer with Shared Serial Ports installed. Our software shares COM1 and enables several applications to use GPS data.

Control serial port signal lines

All hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.) are emulated and supported. As in real null modem connection, DTR of the local port is connected to DSR and DCD of the remote port, and RTS of the local port is connected to CTS of the remote port.

Have several applications access one serial port

Shared Serial Ports allows opening one real COM port by several applications. They are all shown in the Applications list, where you can add/remove applications and set specific access permissions: READ, WRITE, and CONTROL. Default permissions are READ and WRITE, which means applications can read from and write to real serial port, but cannot change its control lines states. By enabling CONTROL rights, you define main applications that can change control lines states.
