Multi-function Serial <-> Ethernet Redirection Software
  • Serial (RS232/USB) to Ethernet interface software
  • Ethernet to RS232 Serial or Virtual COM ports

TCP-Com lets you easily access a serial device via a TCP/IP (or UDP) network or redirect Ethernet/IP data to real or “Virtual” RS232 serial ports. This allows you to use existing Windows-based serial RS232 communications software to send and receive data across any TCP/IP network.

TCP-Com software can be used to easily solve a wide variety of device interfacing and RS232 or TCP/IP conversion problems, such as the following:

  • Turn a PC into a Serial Device Server (Terminal Server)
  • Create Virtual COM ports and send network (i.e. Ethernet) data to them
  • Send or receive data over a TCP/IP port with any serial communications program
  • Open COM ports located on another computer in your network as if they were local
  • Use an Ethernet network (or the Internet) as a giant serial RS232 cable (Serial Tunneling)
  • Feed data from one physical RS232 port to multiple RS232 serial communications applications
  • Map a TCP/IP port to a different TCP/IP port

Use TCP-Com to send Network Data to Real or VIRTUAL Com Ports

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

Use TCP-Com as a Virtual Serial Port Splitter Cable (Learn More)

Windows does not allow multiple programs to access the same COM port. Bypass this restriction by using TCP-Com to split a single COM port into multiple virtual COM ports. This allows all your serial communications programs to access the same data.

Intuitive Multi-Document Interface

In the TCP-Com window just select the com port number and the serial communications parameters for your serial device and enter an IP address and a socket number. Then activate! It's that easy! Com port data will appear at the IP address and data from an IP port will appear at a real or virtual com port.
