Virtual Serial Port 2 TCP 4.0

Virtual Serial Port 2 TCP by Controlbox is a lightweight utility that bridges traditional serial applications with network-connected devices. It creates a virtual COM port on your computer and transparently tunnels its data over TCP/IP—either by connecting to a remote host and port or by accepting incoming TCP connections and exposing them as a local serial interface. This lets legacy software work over a network without code changes or additional hardware.

Key features:

• Virtual COM port to TCP/IP bridge (client or server mode)
• Support for multiple virtual ports
• Emulation of standard serial settings (baud rate, data bits, parity, stop bits, flow control) so existing apps run as-is
• Auto-reconnect and configurable connection parameters
• Connection status indicators and optional traffic logging for troubleshooting
• Compact, low-overhead design suitable for continuous operation

Typical uses:

• Connect PLCs, sensors, label printers, and other serial devices over LAN/WAN
• Access devices behind serial-to-Ethernet adapters or terminal servers
• Extend or consolidate serial workflows without physical COM ports or long cables

Who it’s for:

• Engineers, integrators, and IT teams needing a reliable COM-to-TCP bridge for industrial, lab, or POS environments

In short, Virtual Serial Port 2 TCP helps you keep proven serial workflows while taking advantage of modern IP networks.
