HELP!!! BS2sx and Serial LCD

I've tried downloading the code off of the Parallax website and I've tried writing my own code, and I cannot come up with a way to write correctly to this LCD·from the BS2sx (part no. 27979). HELP!

    You're not really saying what your problem is, but try this code and see what happens.

    ·This is the output I get when I apply your code:

    ········· ******* ***
    *·······*················ *
    ····· *···················*
    ········ ***********

    I'm assuming I should see a border of stars...

    Also, I've used several of the LCD Screens (I had a cpl lying around)... I've also checked and quadruple-checked the switches on the back.

    That is correct, so the display is working...What problems are you having then?

    You're getting confusing...Several Parallax 4X20 Serial LCD Displays?· Or just a bunch of mix-matched stuff?

    then the characters that I enter are coming in irregularly. letters like "A" and "X" and numbers "0" and "8" are not working... That and the command to clear the screen [noparse][[/noparse]12] will not work either

    No no... I'm only using one display at a time. What I meant is that I don't believe the unit is defective unless they all are defective. Both the serial LCD and the BS2sx are bought from Parallax.com.

    My best guess is that you are using the wrong baud rate parameter for a BS2sx...The code I posted automatically substitutes the correct values in based on which BASIC Stamp you are using.· Perhaps you should post your code.

    And when you used that code everything worked...You posted the results yourself.

    No. I said this:
    ········· ******* ***
    *·······*················ *
    ····· *···················*
    ········ ***********
    Came up. Which is very different from a border of stars. How do the power supplies affect the LCD screen (in the paperwork, it mentions that an external power supply is recommended).

    It looked like an ASCII art border with lost formatting...So you're saying the stars are all over the place?· What are you powering it from?
