UART user driver. A UartDeviceDriver must implement all UART functions, but additionally this class provides an open() function that will be called whenever a process obtains ownership of the UART, to match the existing close() function.

UartDeviceDriver ()

Public methods

close

void close ()

Closes the UART. This will be called when the UART is closed by its owner. Any resources that need to be cleaned up should be done so here. This method may throw IOException to indicate I/O failure, but will still be considered closed and may attempt to be re-opened in the future.

Throws
IOException on I/O failure; the driver will still be considered closed.

open

void open ()

Opens the UART. This will be called when ownership of a UART is obtained. The driver should do any initialization needed to configure the UART for use here.

Throws
IOException on I/O failure; the driver will remain closed.
