characters, and provide basic text wrapping so that your text looks right on the display. In addition, the
Serial LCDs also provide you with full control over all of their advanced LCD features, allowing you to
move the cursor anywhere on the display with a single instruction and turn the display on and off in any
configuration. They support the same visible characters as the BASIC Stamp Editor's Debug Terminal

anywhere on the LCD.
