The Parallax 4x20 Serial LCD (Backlit) is very functional, low-cost LCDs that can be easily controlled by a BASIC Stamp® microcontroller. The LCD displays are either two rows by 16 characters or four rows by 16 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 (ASCII Dec 32-127). In addition, you may define up to eight of your own custom characters to display anywhere on the LCD.

This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn't supported by Parallax, but it's possible to make this connection with a few dollars of parts.
