-The ks0073 controller chip, has two sets of, very similar, instructions available, and they are selectable via the Extended Instruction control pin (IE).  In the VLGEM1021 modules this appears to be tied "low".  I assume that this pin is to allow the chip to emulate either of two previous LCD control chip implementations.

-As mentioned earlier the library is based on a standard Arduino HD44780 LCD library.  Most hardware commands, including programmable characters,  seem to be compatible with the HD44780, but I would need to do a lot of experimentation to find any extended commands.+As mentioned earlier the library is based on a standard Arduino HD44780 LCD library.  Most hardware commands, including programmable characters,  seem to be compatible with the HD44780.  There are a number of chip features that are not supported by this driver, such as "Low power mode", "Dot scrolling" (shifting the display window by 1 dot increments), "Bidirectional segment addressing" (horizontal mirroring of display), "4-line mode" (for 4 line displays), "Inverting cursor" and "6-dot font width".  This is mainly because I couldn't test them with the VLGEM1021 LCM.
