I am interfacing a Benq M22 module based GSM modem with my PC and making an application which perform different purposes for SMS. I need to know that which AT command can be used to receive the SMS delivery reports ? I've tried to search AT+CNMI in different modes but this don't work in any case. The other problem I am facing that since I am using the Text mode to send SMS how can I send long SMS, i.e. more than 160 characters? Please help.
Have you tried to get access to the AT command set documentation for the module? It should contain all information you need to know.
This doesn't have anything to do with Keil tools, so it's also Off-Topic here!
