+ *
+ * lcd4linux driver for EFN LED modules (manufacturer: COMFILE/South Korea)
+ * connected to the ethernet to serial converter EUG 100 (manufacturer ELV/
+ * Germany)
+ *
+ * Up to 256 EFN LED modules listen on a serial bus (9600 BAUD, 1 stop bit,
+ * no parity) and are controlled by a 3 byte protocol:
+ * Byte 1: 0xff
+ * Byte 2: <module address>
+ * Byte 3: <Ascii value of character to be diplayed>
+ * The module address of each EFN LED module is set hy solder bridges.
+ * The driver expects the EFN LED modules to be configured starting 
+ * from address 1. The EFN LED module set to address 1 is the right
+ * most module.
+ *
+ * The EUG 100 is an ethernet to seriell converter. The IP address
+ * can be set by dhcp. It listens on ports 1000 (data) and 1001 
+ * (configuration). Data received on port 1000 is sent onto the serial bus, 
+ * while data sent to configuration port sets format of the EUG 100's 
+ * serial interface.
+ * Due to a bug in the firmware, the transmission is interrupted if '\0' (0x00)
+ * is received on port 1000. Consequently, none of the EFN LED modules shall
+ * be set to address 0.
