USB Over IP Software


Multi-function Serial <-> Ethernet Redirection Software

TCP/Com Terminal Server software converts your PC into a USB or Serial to Ethernet converter. Converts USB to TCP/IP.

Add a single or multi-port serial adaptor to your Windows PC, attach your existing serial (RS232) devices to your PC and use TCP-Com to send the serial device data across TCP/IP networks – Ethernet or Internet.

“Share serial devices over a network (or even the internet)”


  1. 1) Download free 30 Day evaluation version of TCP/Com to Windows PC.

  2. Attach USB device to the USB port on your PC. Install the USB to RS232 driver software that comes with the USB device. This will create a virtual RS232 COM port. Most USB measuring devices - scales, gages, meters, analyzers, etc. – offer a USB to RS232 driver.

  3. Select that virtual COM port in TCP/com window. Also select the baud rate, parity, data bits, stop bits and flow control options for your serial device.

  4. Select “This PC will act as a TCP server”.

  5. Activate TCP/Com and your USB serial device data is now available over your TCP/IP network.

Notes: All communications are fully bi-directional and real-time.

USB Over IP Software: TCP/Com Software is extremely simple but powerful. It can be used to solve a wide variety of device interfacing and RS232 or TCP/IP conversion problems, such as:

  • 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 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 one TCP/IP port to a different TCP/IP port

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.
