W&T COM Port Redirector Legacy 3.94, developed by Wiesemann & Theis GmbH, is a network-serial bridging utility that creates virtual COM ports on Windows systems so that legacy applications expecting local RS-232/485 interfaces can communicate transparently with remote W&T devices such as Com-Server, LAN-Modem or Web-IO equipped with serial ports. By encapsulating serial data in TCP or UDP packets, the driver enables standard accounting, measurement, automation or POS software to operate over a LAN or WAN without modification, eliminating the need for physical cable runs and extending the reach of equipment already deployed on the shop floor, laboratory or office. The package is offered in two concurrent versions—this “Legacy” line and a newer “PnP” line—both maintained for customers whose operating-system policies or application certifications demand the older codebase; administrators should note that wt-com-pnp must be uninstalled before installing wt-com-legacy to avoid driver collisions. Typical scenarios include centralizing CNC machine monitoring, connecting modems for remote diagnostics, linking barcode scanners to warehouse servers, or enabling legacy DOS/Windows ERP tools to poll scale indicators across buildings. The driver supports Windows 7 through Windows 11, automatically maps up to 256 ports, and integrates with the Windows Device Manager for baud-rate, handshake and port-number assignment. W&T COM Port Redirector Legacy is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, guaranteeing the latest 3.94 build and supporting batch installation alongside other applications.
