Ethernet to Serial “Cable” Converter Software, TCP-Com

How to redirect Ethernet data to real or “Virtual” serial (RS232) ports using TCP-Com software from TALtech. It converts your Ethernet to serial even creating a Virtual RS232 serial port if needed.

TCP-Com is a Six-in-One Ethernet to Serial tool:

One: Convert Ethernet to Serial (RS232). Even create virtual COM ports to receive network data. This allows you to send or receive data over Ethernet or any TCP/IP network using any existing COM port software.

Some software only recognizes data coming from serial RS232 COM ports. TCP-Com can easily create virtual COM ports and redirect Ethernet, Internet, or network data to these serial COM ports. This allows you to use any existing serial communications software to communicate over and collect data directly from your IP networks.

Network Data Redirected to real or VIRTUAL serial COM Ports

2. Share devices over a network

Use TCP-Com as a PC-based serial device server (also known as a Terminal Server) to make any device accessible on a network.

Attach serial devices to your PC’s serial RS232 or USB ports and TCP-Com will make the data available at an IP address (and port number) on your network. Add additional USB or RS232 ports to your PC to make TCP-Com act as a multi-port Serial Device Server or Terminal Server.

3. Feed RS232 COM port data to multiple PC apps or COM ports

Use TCP-Com as a virtual splitter cable.

Windows does not allow multiple applications to access the same COM port. Bypass this restriction by using TCP-Com to split a single COM port into multiple Virtual COM ports (which TCP-Com creates). This allows all your existing serial communications applications to access the same data.

4. Use an IP network as a giant RS232 cable

5. Open network COM ports as local COM ports

6. Map one network port to another network port
