I am confident that the baud rate is not a problem. Otherwise none of the commands I am sending to the module would result in the results I am seeing posted on the web site.
Yes, I am seeing the OK returns on the commands, so I don't think that is a problem.
Just the fact that my command to send the array sereial_no[ ] ends up with the same value posted on the web site that I am reading back from EEPROM tells me that the commands are getting through.

However, I don't understand what you mean by "inverted data"....can you please explain?
