I use lcd display like this and it works well 

FILE *lcd;  lcd = fopen("/dev/lcd_display", "w");  /* Write some character to the LCD. */  if (lcd != NULL )  {  fprintf(lcd, "%c", ESC);  fprintf(lcd,"[%c", y);  fprintf(lcd, "%c", ESC);  fprintf(lcd,"%cH", x);  }  fclose( lcd ); Many regards Marcin.
