LinkTap
Open the middle of a device link and read what passes — no separate install.

What it does
- —Passive capture (Windows): watch a link like Wireshark, capture driver bundled — admin only, nothing to install
- —TCP proxy: point the client at LinkTap, it forwards to the real server — no driver
- —Serial bridge: device on port A, application on port B, no kernel driver
- —Modbus TCP/RTU and NMEA 0183 recognised and decoded to one line each
- —Direction is known, not guessed — a client frame is a request by construction
