TCP COM Bridge - connects two physical or virtual COM ports to each other over network!

For Windows 2000 - Windows 11 (2022) (incl. Server, x86 and x64). Latest version: 1.7.8 build 729. July 29, 2022.

TCP COM Bridge - connects two physical or virtual COM ports to each other over a network!    

Brief description:

TCP COM Bridge is a utility program that works as an RS232-TCP/IP software converter and allows to forward data from a physical or virtual COM port to an Ethernet network. Using this program, you can turn any computer into a "serial device server." TCP COM Bridge lets you create a connection between two COM ports on two different computers, even via the Internet. This way, you can build distributed data collection systems using legacy software that supports COM ports only.

What problems can be solved with TCP COM Bridge?

TCP COM Bridge lets you save money on buying hardware serial device servers, as a computer running the program can easily do the same task. You can connect or create up to 256 COM ports on one computer, which will simultaneously handle up to 256 RS232 devices. Typical usages are described here.

Getting started is easy. TCP COM Bridge is ready!

After installing TCP COM Bridge, start it from the "Start->Programs" group. The program will ask you about creating a new connection. You should click the "Yes" button and select COM port and IP settings in a dialog window. Click the "OK" button in the dialog window. Now, your TCP-COM connection is ready.

Network. You can transmit data using the TCP and UDP protocols both in the local network and over the Internet.

Flexibility. When enabling data exchange over the Internet, TCP COM Bridge can handle dynamic IP addresses via a domain name.

Use locally. You can also create local connections on one computer.

Serial port splitter. You can split data from one COM port into two or more streams (that is, use the program as a serial port splitter).

Serial port sharing. The program allows you to use one COM port from two or more applications.

Service mode. TCP COM Bridge can be automatically launched as a service, create virtual COM ports, and set up network connections even before any user logs on to the system.

Software reliability. Our drivers for virtual serial ports had been tested with the verifier under all modern OS since Windows XP SP2;

Hi-tech. TCP COM Bridge uses kernel driver technology and supports WDM, WMI, Power Management, PNP, etc.;

Easy-to-use. TCP COM Bridge software has a simple, menu-driven step by step set-up. Programming is not required to configure the software to configure virtual serial ports and COM-TCP connections;
