I'd like to change the startup screen on a LK202-25WB (installed on a linux system). I' using the following perl code.
open(LCD, ">/dev/lcd") or die "Can't open (write) to /dev/lcd: $!\n";
print LCD chr(254), chr(64), " WELCOME! BOOTING SYSTEM ";
close(LCD);
Unfortunately this code is not working

Other thinks work fine. I can clear the display, turn backlight on or off, ...
Do i need to use the remember function to set the startup screen?
Maybe somebody can help me.
Thanks!
Regards,
Robert
