ViewMarq RS-232 to Allen Bradley MicroLogix 1400

Has anyone successfully written a command string to the ViewMarq from the MicroLogix? I have written the code per the example in the manual and I have verified communications by programming the ARL (ASCII Read Line) per the manual. When I send the command to the AWA (ASCII Write Append) I immediately get a response from the ARL but the response is not the typical 'OK^M^J' but instead it mirrors the command I sent it and appends the command with a ^M.

Example:

Command: <ID 1><CLR><WIN 0 0 287 31><POS 0 0><SL><S S><BL N><CS 0><GRN><T>Hello Duke</T>

 

Response from ARL:

<ID 1><CLR><WIN 0 0 287 31><POS 0 0><SL><S S><BL N><CS 0><GRN><T>Hello Duke</T>^M

 

Any suggestions would be greatly appreciated!

    I haven't from a 1400 but I have from a SLC 500 and it works fine.

    I was about to ask if AWA (vs AWT) is the correct instruction, but it seems that the whole string is getting out and back in.
