* - built for parport version of this interface: Wallbraun Electronics lcdinterface
* (specifications here: http://wallbraun-electronics.de/produkte/lcdinterface/index.html)
* - wiring scheme used: "bitshaker" (called "yasedw" in serdisplib)
* --> default wiring: wr=16; a0=17; rd=01; cs=14
* --> yasedw wiring: wr=01; a0=14; rd=16; cs=17

* --> classic wiring: wr=16; a0=17; rd=01; cs=14
* --> bitshaker wiring: wr=01; a0=14; rd=16; cs=17
* December 2006, Benjamin Wiedmann (additional changes, fixup)
* - wiring scheme can now be changed at run time using "ConnectionType" config parameter
* in sed1330 driver section
* Usage of ConnectionType in LCDd.conf:
* ConnectionType=<classic|bitshaker>
* - if no ConnectionType is set it defaults to "classic" wiring
*
* IMPORTANT: MODULES OTHER THAN G321D
* ===================================

* You can also change the wiring scheme by using the ConnectionType= option:
* ConnectionType=<classic|bitshaker>
* If not set, classic wiring is used.
*
* The port= value should be set to the LPT port address that the LCD is
* connected to. Examples:
* port=0x378
