GLK12232-25-SM supports 115200 or 57600 bps?

I set to that speed then send a text through mogd.exe, I notice many drops. If I send 'Matrix Orbital', it shows 'MaOrb'.
Maybe my serial cable, it is 20cm length shield cable but not exactly for the data communication.

But please let me confirm that ...

I was trying to almost samething on Windows. My LCD is GLK12232-25-SM, so it may different, but try to read longer than 1 byte. In my case, I read everything from read queue and could find pressed key code at the end of the bytes. I found this when I am tracing the port data.

Since it is taller then 3.5 bay, need some case modification.
CD Drive's bottom plate must be removed or cut.

While I am waiting a new unit ( because the unit has a stablility issue),
I am developping a software that shows system status. Now it is working.

One problem is: At the end of program, it could not turn off the flow control, or clear screen. It works using MS debugger, but not work without.
Any ...

Okay, now I go through the rma procedure.
Thank you.

Nothing has changed even if I do not connect the serial cable. Just got black or blank screen, depends on the LCD status, but never get intial screen.

So normal LCD should show intial screen, right?

Just one more question.

My power connector of LCD is connected to my PC.
When I power my PC on, LCD is also powered on.
In this case, I had no chance to see the intial screen.
I confirmed with my three PCs and never.

If I power my LCD on after PC was started up, it seems to be working.
But must be ...

Okay, I sent email.

Thank you.

Update:

Once I could get it works, I send a text using mogd.exe, and shutdown the PC (power off). After that, I power it up, I do not get the initial scree, or black screen. Of course the LCD does not accept to show any text or graphic. It is time to RMA, right?

Yes, I did.

I am always trying the over ride method. To do that, I put a push switch between 5 and 6 pin. Well, it sometimes work, but in many case, it does not. I do not know why. One night I could not sucess, but next morning, it suceeded :oops: . Once it recoverd, everything works fine :lol: . But again ...

I tried. Under that situation, I could change the contrast, and could save the level. But could not write any text or image.

When I got all black screen, the LCD can change the contrast, accept the font download, but never shows any text even after I adjusted the contrast. I can not draw graphic either. Once it entered this mode, after power off-on, it goes normal contrast without initial screen and never accept to show ...

I got GLK12232-25-SM last week and trying to work stably, but could not.
It SOMETIMES shows the start up screen, but many times, NOT.

When the LCD is powered up with PC, it shows black (full dots are ON) screen. If I leave it, it goes strange status. Under the status, I can control back light or ...
