Author How to speak with the GSM Modem (HTC SDA)

Hi,

I have a SDA smartphone from HTC (T-Mobile, OS: WM 2003). I need a GSM
connection (no GPRS) in my visual c++ program.

If I open a serial port and send "AT\r\n", I will get nothing back. I tested
on port COM1 to COM10.


I need a GSM connection from mobile phone to mobile phone and from mobile
phone to ISDN.

How can I start a connections?


Are there library or samples?



Thanks



Tom

no, this isn't publicly documented. you need to look into the RIL library.
