Question : Again, Detecting arrival of new SMS Messages!

Hi there,

 As a new SMS-Programmer, I'm still confused with detecting arrival new SMS messages, regardless of previous discusions in this group.

And what are my problems Now ?

 1 - Can  I detect that a new SMS message event-driven(if yes, How?), or Should I use a polling method(say Checking my SIM-Card memory with AT+CMGL)
 2 - How can AT+CNMI help me to detect new SMS's? How should I call it?(Which parameters)
 and how can I detect new messages, then ?

Any guideline would be of great help.
Thanks,

--Reza

Answer : Again, Detecting arrival of new SMS Messages!

As somebody mentioned in your previous question, it is possible to get a notification of an unread SMS when doing other commands (you get a +CMXX: or something like that mixed in with the responses).  I found this unnecessarily complex.
