I think my GLK12232 Copped it
1.9 Manual Override
Manual override should only be required in one instance. If for some reason the module is set at a baud rate which cannot be produced by the host system and all communication to the display is lost, then the user should follow this simple procedure:
Turn off the display
Put a jumper on pins 5 and 6 of the keypad connector.
Power up the display. The baud rate is now set to 19,200.
Remove the jumper and change the RS-232 port settings to the desired baud rate.
Turn off the display.
Power up the display.
Refer to the "Set RS-232 Port Speed" command (section 7.1.10) for acceptable baud rates.
Note: This procedure does not change settings in the memory chip, it uses default settings stored in the main processor. This allows the user to communicate with the display when all other communications are lost. Once able to communicate with the display, the user may then change the default settings in the memory chip.

I received yesterday my GLK12232, and found similar problems to the ones described here.
I first had trouble getting mogd to display "Matrix Orbital Graphic Demo". The LCD wanted to display "MatDe" only. Changed COM speeds several times only to get different results but nothing much better. The graphic tests went OK.
Suddenly it started working.
I tried LCDCenter, LCDStats and Smartie (all in the latest versions). Not a single one of this programs worked fine. Most of them could display only the "first screen" programmed, and following screens just overlapped on top.
I enabled the auto-scroll, and things got much better, but i still had some overlapping.
I replaced the fot in position 1 to "small font" (not "clear"), and programs were more "useable", but still nothing perfect.
LCDStats is the one that worked better, but still, the LCD sometimes "hangs", and I have no other option than to power it down, try mogd.exe, and if it doesn't work, reload the fonts again, load a graphic and try mogd tests again.
I always have control of backlight and contrast (as someone mentioned before too).
