Communicating with TWR-LCD standalone

I have a project where I'm using a TWR-LCD as a standalone device, running a program loaded via the USB bootloader.  It is not connected to the tower system/elevator, so (as I understand it) the MCF51JM128 microcontroller is controlling the LCD screen.

 

What's the best way to allow this program to communicate with an external device?  I just want to send/receive some simple serial data, not directly control the LCD screen, but I'm not sure how to go about it.  Unfortunately none of the example applications for the TWR-LCD seem to deal with this, and I'm rather new to embedded programming.

 

Any help or advice would be greatly appreciated!
