Serial and hardware-style links

Enable serial_telemetry_port to stream telemetry through the guest’s gatos.serial virtio device. Enable serial_command_port to accept the small SCPI control vocabulary on that same link. In the guest, the device is available at /dev/virtio-ports/gatos.serial.

Telemetry can use ndjson, nmea, or ccsds framing. Configure the cadence with serial_interval_ms. This is a focused bus-style connection for a cockpit toy, external program, or protocol experiment. It does not reproduce all /sim files.

head -n1 /dev/virtio-ports/gatos.serial
printf 'CTL:IGNITE\n' > /dev/virtio-ports/gatos.serial

The live serial bridge has guest integration coverage, but the full KSA flight validation pass is still open. CCSDS and MIL-STD-1553 configuration switches are reserved for future dedicated bus transports. They do not expose a bus today.

See the serial reference for framing details, SCPI commands, and configuration.
