<> 144:ef7eb2e8f9f7 23 * operations with "streams" of data, such as UART devices, SPI or I2c, etc.
<> 144:ef7eb2e8f9f7 24 *
<> 144:ef7eb2e8f9f7 25 * The character driver derives from the generic driver template (see driver.h).
<> 144:ef7eb2e8f9f7 26 * It does so by including an element of the generic driver_t type.
<> 144:ef7eb2e8f9f7 27 *
<> 144:ef7eb2e8f9f7 28 * The driver defines blocking and non-blocking read and write operations. It is
<> 144:ef7eb2e8f9f7 29 * up to the driver implementation to decide which of these to actually implement.
