Cool, I'm glad you can use it. Before you start looking at LCDs with serial interfaces, make sure that it supports TTL-level signaling and the baud rates that this software supports. For ease of use, I'd suggest looking at LCDs that support serial terminal-like interfaces too.

Of course, you're best bet is to find a LCD that can use the hardware serial ports built into the EDU controller (and presumably the full-size controller). If you want to use the dedicated TTL-level serial port, make sure that your LCD supports non-inverted TTL-level signaling.

Here is an great web page that discusses the different ways to communicate with a serial LCD: http://www.seetron.com/ser_an1.htm
