Thanks Troy. I got it working.

Hi,

I've got an Visual Studio 2013 C# application to control the EGLK19264A-7T-USB-WB-PL display.
All worked fine with version 8.4. Now I have a big problem with setting the font ID using version 8.5.
All other commands I send to the display work fine.

Can you help me?
And could you please supply ...

Hi Martino,

Thanks for your reply.

The problem was that I had to wait 50 milliseconds for the display.
So I added this line:

comport.Write(commando2Bytes, 0, commando2Bytes.Length);
int milliseconds = 50;
Thread.Sleep(milliseconds);

regards
Paul

When I execute this code (visual studio, C#):

//Read module type
commando[0] = 254;
commando[1] = 55;
port.Write(commando, 0, commando.Length);

int length = port.BytesToRead;
byte[] buf = new byte[length];
port.Read(buf, 0, length);
Console.WriteLine("Received data: " + buf);

I don't get ...
