Re: Real time SMS system
I advice you to program it in C, you may use KEIL.Don't use Assembly for this.Secondly you have all AT commands given in your WaveCom Modem.Although AT commands are generally common to most of the modem, but still it's better to check it's AT command manual.

My friend made a similar kind of project, it took him 3 months to make it, that was related to Vehicle Security system and it was working on SMS system.It also had a GPS facility.Although being a friend, he let me have his code.It was a massive code.If he would have written it in C, he would have save so much time.
You better experiement AT commands on Hyper Terminal as a first start.Make your program over there.
Once you get confident in your AT commands.You then use controller to transmit those AT commands and process them.
