BSP and Device Driver Development Guide
The console_control is invoked when the line parameters
for a particular serial device are to be changed.
This entry point corresponds to the device driver
io_control entry point.
The application write is able to control the serial line configuration
with Termios calls (such as the ioctl command, see
the Termios documentation for
more details). If the driver is to support dynamic configuration, then
is must have the console_control piece of code. Refer to the gen68340
BSP for an example of how it is done. Basically ioctl
commands call console_control with the serial line
configuration in a Termios defined data structure. The driver
is responsible for reinitializing the UART with the correct settings.
