 * @details
 * A UART driver must comply to the generic driver template (see driver.h), and
 * more specifically to the character driver template (see char_driver.h). All
 * UART drivers share some properties; defining these is the purpose of this file.
 *
 * The options passed when opening a UART device should at least include the
 * flow control type and the baud rate. These are included in the uart_options_t
 * data type. The type can be extended by a UART driver implementation.
 *
 * The UART driver implementation must make its driver publicly available with
 * an external global variable.
