<> 144:ef7eb2e8f9f7 28 * A UART driver must comply to the generic driver template (see driver.h), and
<> 144:ef7eb2e8f9f7 29 * more specifically to the character driver template (see char_driver.h). All
<> 144:ef7eb2e8f9f7 30 * UART drivers share some properties; defining these is the purpose of this file.
<> 144:ef7eb2e8f9f7 31 *
<> 144:ef7eb2e8f9f7 32 * The options passed when opening a UART device should at least include the
<> 144:ef7eb2e8f9f7 33 * flow control type and the baud rate. These are included in the uart_options_t
<> 144:ef7eb2e8f9f7 34 * data type. The type can be extended by a UART driver implementation.
<> 144:ef7eb2e8f9f7 35 *
<> 144:ef7eb2e8f9f7 36 * The UART driver implementation must make its driver publicly available with
<> 144:ef7eb2e8f9f7 37 * an external global variable.
