  Installation is pretty simple: Run 'make config' and after this 'make' or
 'make install' to get the binary installed in /usr/sbin.

 Config options:
		 address	  :  The base address of the lp-port you want
				     to use, usually 0x3bc, 0x378 or 0x278.
				     The default is 0x378. (The 0x stands for
				     the hexadecimal notation --
				     VERY IMPORTANT!)
		 update-delay	  :  The delay between display-updates.

 This values can later be overridden using command-line options.

  To connect a display to a printerport, you just need the double display and
 some cable, the plug for the port and the display itself, with shared kathode,
 2 digits and the pinout.

  The printerport is numbered as follows, if you look at it:
	______________________________________________
	\					     /
	 \  13 12 11 10  9  8  7  6  5  4  3  2  1  /
	  \					   /
	   \  25 24 23 22 21 20 19 18 17 16 15 14 /
	    \____________________________________/

  The pinout of the display, when you look at the pins:


	 _________
	| ___a___ |
	| |	| |  Kx are the shareded kathodes,  the  two pins per display
	| f	b |  are usually  internal connected.  All you have to do now
	| |	| |  is to connect the pins of the port-plug  and the pins of
	| |__g__| |  the display as follows:
	| |	| |
	| e	c |	a - 2	e - 6	K1 - 14   K1 means the cathode of the
	| |	| |	b - 3	f - 7	K2 - 16   right display, K2 means the
	| |__d__|i|	c - 4	g - 8		  cathode of the left display.
	|_________|	d - 5	i - 9
	  This 2x

	Note that you can't use two single displays, since you MUST HAVE one
	double-display (14-segment) with one connection-set for both displays!
	Note K1 and K2 (pinout-description of the display).
 
	Be safe doing this - a short between two pins mey reult in a destroyed
	printerport. According to this, DO NOT USE ON-BOARD ports, as a damage
	of the port may result in a defective chipset!

	Jepp, that's it. Enjoy it, hate it or whatever.
