D03-RT: Yes
Rationale
The selected Reticulum 1.5.5 SerialInterface can connect ordinary serial ports directly over a wire pair. A commodity serial port or USB serial adapter suffices; a radio, RNode or other specialized transceiver is not mandatory for this selected serial profile.
Assessment method
Documentary resolution; no new runtime, cryptographic attack or hardware test
Source context
Primary documentation and explicit selected-profile analysis, reviewed 2026-10-15
Outstanding qualification
Serial hardware and ordinary OS drivers remain required. This does not qualify a radio deployment or physical-link performance.
