The TOBY-L4 exposes multiple TTY ports, but each of them has different purposes: The TTY at interface #2 is a fully capable AT port but shouldn't be used to start connections, so we flag it as secondary. The TTY at interface #4 is a non-AT debug port, so we explicitly ignore it to make probing faster. The TTY at interface #6 is the fully capable AT port that must be used as primary port. The TTY at interface #8 is an AT-capable port but dedicated to FOTA update operations.
