HwProgramUART

Configure the settings for the device’s universal asynchronous receiver/transmitter (UART).

Declaration

virtual kern_return_t HwProgramUART(uint32_t baudRate, uint8_t nDataBits, uint8_t nHalfStopBits, uint8_t parity);

Parameters

  • baudRate:

    The baud rate requested by the system.

  • nDataBits:

    The number of data bits to transmit.

  • nHalfStopBits:

    The number of half stop bits. For example, specify 3 to generate 1.5 stop bits.

  • parity:

    The parity setting to use during communication. For a list of possible values, see Parity Options.

Return Value

kIOReturnSuccess on success, or another value if an error occurs. See Error Codes.
