read_serial
Capture UART output from a connected board with configurable baudrate, port, and optional text matching or reset on open.
Instructions
Capture bounded UART output through the shared serial-resolution and UART services.
Defaults come from the connected board config only for baudrate and
serial-port selection heuristics. ``expected_text=None`` means no explicit
text expectation: any observed UART output counts as a match.
Set ``port`` to override serial resolution explicitly. Set ``reset_on_open``
to trigger a target reset immediately after the UART port opens so early
boot text is captured deterministically.
