Shared Serial Ports

Shared Serial Ports ensures simultaneous, high-speed, bi-directional and collision-free connection to RS232 serial port for unlimited number of applications. All applications that connect to shared COM port will be able to communicate (send and receive data) with the device which is attached to real port as if they had an exclusive access to that device. As a result, Shared Serial Ports application lets you bypass one-application-per-one-serial-port limitation and provide certain applications with custom access rights. If you would like to implement Shared Serial Ports' great functionality into your software, OEM license will provide you with all rights needed for that.

With Shared Serial Port you can:

Share one port for many applications
Shared Serial Ports creates any number of virtual copies of a real RS232 serial port and invisibly gives them the same names. For example, you share your COM1 port with Shared Serial Ports. Thus, you will have any number of COM1 ports in your system, which serve as common physical ports to all applications and ensure precise data transmission from a serial device to all applications.

Make several applications control shared serial port
Shared Serial Ports provides you with the ability to open one COM port by several applications. All of these applications are shown in the Applications list, where you can add/remove them and set specific access permissions, such as read, write and control. Read and write permissions are set by default, meaning that applications will be able to read from and write to real serial port, but will not be able to change its control lines states. By enabling control rights, you give the right to change control line states to the specified application.

Control serial port signal lines
Virtual ports, created by Shared Serial Ports emulate and support all hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.). 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.

Full features list:

• Provide simultaneous access to a single serial port for multiple applications
• Unlimited number of applications are able to work with one device (serial port) simultaneously
• Flexible access policy for each application (read/write to serial port; manage control lines)
• Useful on-screen visualization of shared serial ports, connected applications and communication activity (sent/received bytes, status, etc.)
• RS232 specification standard compliant
• Customize real serial port connection parameters (baudrate, parity, flow-control, databits and stopbits)
• Bidirectional data transfer
• Unique sharing technology
• Completely transparent operation
• Fully compatible with Windows 2000/XP/2003/Vista
• High speed data exchange from/to serial port (up to 256 kbits)
• "Hot" installation - no reboot required either for installation or for creation of virtual serial ports
