ComLinkerTCP Serial Bridge

TCP to COM port bridge

Connect TCP/IP devices to COM-port software on Windows.

ComLinker creates a local virtual COM port and binds it to a remote TCP endpoint. Your existing Windows application opens the COM port as usual while ComLinker handles the TCP connection.

When this helps

Use a TCP to COM bridge when a PLC, meter, DTU, gateway, or serial device server is reachable over Ethernet, but the Windows software still expects COM10, COM11, or another local serial port.

Typical workflow

  1. Create or select a virtual COM port.
  2. Add the remote IP address and TCP port.
  3. Start the binding in ComLinker.
  4. Open the COM port in the legacy application.

Deployment notes

ComLinker is built for practical Windows field deployments, including Windows Server environments, auto reconnect, connection monitoring, and diagnostics export for support.

Trial before purchase

The 14-day trial lets you verify your TCP endpoint, virtual COM port, and target Windows software before buying a one-time workstation license.
