The W&T COM Port Redirector Plug & Play 4.47 from Wiesemann & Theis GmbH is a systems-utility component that turns networked Com-Servers or Web-IO devices equipped with a serial interface into ordinary Windows COM ports, enabling legacy RS-232/RS-485 applications to operate transparently over Ethernet or Wi-Fi without code changes. Designed for industrial automation, laboratory instrumentation, POS, medical, and building-control environments, the driver intercepts Win32 CreateFile calls directed at COM3, COM4, etc., encapsulates them in TCP or UDP frames, and forwards them to the remote device; return traffic is injected back into the application exactly as if a local UART had generated it. Because the assignment is Plug-and-Play, newly detected Com-Servers appear automatically, and ports can be limited, renamed, or grouped through a straightforward management console that also logs traffic and signals connection loss. The 4.47 release, the sixth public build since the product’s introduction, adds support for Windows 11, improves latency at 921 600 baud, and signs the driver package with Microsoft’s current attestation certificate so it installs without disabling Secure Boot. Administrators who need to scale deployments can pre-configure an INI file containing IP addresses, TCP ports, and desired COM numbers, allowing silent rollout via SCCM or Intune. By removing physical cable length limits and making serial devices addressable from any VLAN, the redirector facilitates centralized data collection, virtualized production lines, and remote maintenance while preserving proven SCADA, label-printer, or calibration software that expects a local port. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
