Struct rppal::uart::Status

pub struct Status { /* fields omitted */ }

Control signal status.

Implementations

impl Status

pub fn rts(&self) -> bool

Returns true if RTS is active.

RTS (active low) is controlled by Uart. An active signal indicates Uart is ready to receive more data.

pub fn cts(&self) -> bool

Returns true if CTS is active.

CTS (active low) is controlled by the external device. An active signal indicates the external device is ready to receive more data.

pub fn dtr(&self) -> bool

Returns true if DTR is active.

DTR (active low) is controlled by Uart. When communicating with a modem, an active signal is used to place or accept a call. An inactive signal causes the modem to hang up. Other devices may use DTR and DSR for flow control.

DTR is not supported by the Raspberry Pi’s UART peripherals, but may be available on some USB to serial adapters.

pub fn dsr(&self) -> bool

Returns true if DSR is active.

DSR (active low) is controlled by the external device. When communicating with a modem, an active signal indicates the modem is ready for data transmission. Other devices may use DTR and DSR for flow control.

DSR is not supported by the Raspberry Pi’s UART peripherals, but may be available on some USB to serial adapters.

pub fn dcd(&self) -> bool

Returns true if DCD is active.

DCD (active low) is controlled by the external device. When communicating with a modem, an active signal indicates a connection is established.

DCD is not supported by the Raspberry Pi’s UART peripherals, but may be available on some USB to serial adapters.

pub fn ri(&self) -> bool

Returns true if RI is active.

RI (active low) is controlled by the external device. When communicating with a modem, an active signal indicates an incoming call.

RI is not supported by the Raspberry Pi’s UART peripherals, but may be available on some USB to serial adapters.

Trait Implementations

impl Debug for Status

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
