+ * 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.
