Answer
S Registers need to be set on the Ezurio Terminal to enable Multipoint mode on the BT730. To do this, follow these steps:
Start Ezurio Terminal
Enter “ATS127=0x200” (this will enable Multipoint mode)
Enter “AT&W” to save/write your settings
Power cycle the BT730 then start the Multipoint Terminal
Additional information on Multipoint can be found in Chapter 2 of the Firmware User Guide.
