Virtual COM Port Driver 1.4

Virtual COM Port Driver is a utility that creates software-based serial (COM) ports on Windows, allowing applications designed for physical serial hardware to run without it. It can generate virtual port pairs linked by a software null‑modem connection, so data written to one port appears on the other. This is especially useful for testing and debugging serial applications, connecting legacy software to modern systems, and simulating serial devices during development.

Key capabilities:

• Create and manage multiple virtual COM ports and port pairs
• Emulate null‑modem links with configurable baud rate, data bits, parity, stop bits, and flow control
• Preserve port names and settings across reboots
• Support both 32‑bit and 64‑bit applications that communicate via standard Windows serial APIs
• Optional logging and diagnostics to trace serial data exchange

Typical use cases include software QA, driver development, integration with legacy serial workflows, and scenarios where hardware access is limited or impractical (for example, replacing physical loopback tests). The result is a flexible, hardware‑free way to develop, simulate, and interconnect serial communications on modern Windows systems.
