Here's one I wrote for my own use. Not much in the way of features, but it does work.
lcdecho line1 line2 line3 line4 /i
*Can display up to 4 lines of text.
*Assumes that the lcd is connected to COM1.
* /i is optional, it initializes COM1 to 19200 baud
*Use the underscore character to display a space on the lcd
Ex: lcdecho some_text_here
will display one line of text:
some text here
