<> 149:156823d33999 28 * The character driver is intended for devices that allow read and write

<> 149:156823d33999 30 *
<> 149:156823d33999 31 * The character driver derives from the generic driver template (see driver.h).
<> 149:156823d33999 32 * It does so by including an element of the generic driver_t type.
<> 149:156823d33999 33 *
<> 149:156823d33999 34 * The driver defines blocking and non-blocking read and write operations. It is
<> 149:156823d33999 35 * up to the driver implementation to decide which of these to actually implement.
