Virtual Serial Port Driver for Windows

Product snapshot

Virtual Serial Port Driver from Eltima creates software-based COM ports and links them together with a virtual null-modem connection. This lets programs communicate as if they were connected by a physical serial cable while no extra hardware is required.

How it operates

When two applications are attached to a paired virtual port set, they can send and receive data between each other just like with real serial ports. Each virtual COM port appears in the system’s Device Manager and behaves according to its configured parameters, reflecting active port settings and runtime status for easy inspection.

Key advantages for users

• No need to install extra physical serial adapters — you can provision virtual ports on demand.
• Eliminates clutter and hardware constraints in environments that require many serial interfaces.
• Real-time visibility and management of virtual ports through the operating system’s device view.
• Accurate emulation of port settings and behavior so legacy software continues to function without modification.
• Enables direct data exchange between paired applications without additional bridging software.

Compatibility and integration options

• Kernel-level driver support for deep system integration and reliable operation.
• Standard DLL interfaces for incorporating port control into other programs.
• Component technologies such as ActiveX for integration with automation and scripting environments.

Recommended free substitute

If you prefer a cost-free option, consider the Free Virtual Serial Ports Emulator — a no-cost tool that offers similar virtual COM port creation and pairing capabilities for basic testing and development needs.
