SolarOS 4.6.8 manual · app

com

Serial terminal for a bidirectional byte-stream port. Display-keyboard or port-shell input is forwarded to the selected port, and received bytes are drawn in the active terminal. The port may be a UART or a virtual port such as a peer-bound SolarOS Link stream.

Usage:

com [--autobaud] [--hex] [port]

The port defaults to uart0. For example, com gps connects to an existing runtime UART bus named gps, while com vser0 opens a Link stream previously created with link stream create. The selected port remains claimed by the app until the session exits. com works from both display and port shells; when launched from a port shell, its terminal output is returned through that same port. The input/output shell port and selected COM port must be different.

--autobaud is available only for UART buses. It samples the RX signal for three seconds before opening the terminal. Send a repeating 0x55 or 0xaa pattern during that interval. A reliable measurement is matched to a standard UART rate and applied to the current bus connection without overwriting the saved baud setting. UART input forwarding begins when sampling completes. If measurement fails, the configured rate is kept.

--hex displays received bytes as eight-byte offset, hexadecimal, and ASCII rows instead of interpreting them as terminal text. Both options can be used together.

Examples:

com --hex gps
com --autobaud --hex uart0
com vser0

Controls:

• App-exit key exits.
