+ * driver for a simple serial terminal.
+ * This driver simply send out caracters on the serial port, without any
+ * formatting instructions for a particular LCD device.
+ * This is useful for custom boards of for very simple LCD.
+ *
+ * I use it for tests on a custom-made board based on a AVR microcontroler
+ * and also for driver a Point-of-Sale text-only display.
+ * I assume the following :
+ * - CR (0x0d) Return to the begining of the line without erasing,
+ * - LF (0x0a) Initiate a new line (but without sending the cursor to
+ * the begining of the line)
+ * - BS (0x08) Erase the previous caracter on the line.
+ * - It's not possible to return to the first line. Thus a back buffer is used
+ * in this driver.
+ *
+ * The code come mostly taken from the LCDTerm driver in LCD4Linux, from
+ * Michaels Reinelt, many thanks to him.
+ *
+ * This driver is released under the GPL.
