I just got one of those new LG 9800s from Verzion and I thinking about interfacing a microchip to the phone. I have seen how to do this with a GSM phone through the use of AT commands, but nothing on CDMA phone.

Does anyone have any experience sending AT commands over rs232 to a CDMA phone? In particular I am trying to see if it is possible to send a Flash SMS message.

I can handle the rs232 part, its the CDMA command structure that I need help with.

Thanks in advance for any ideas
