Objective is to develop an application by which we will be able to Send,receive & delete SMSby using GSM modem as hardware tool and visual studio as software programming tool . . . .
We will provide code which will be in C# language by which we will receive, send &delete messages by using graphical interface and GSM modem as hardware tool and c# language as for the purpose of execution of commands. .
We will use HyperTerminal in order to check AT commands… AT commands are attention commands which help us to communicate with the modem… i.eAT+CMGF=1 , AT+CPMS="SM" ,AT+CMGS="…… these are some commandswhich help us to send, receive ,delete & count sms. .
This project is useful as practical project for computer science students which can be implemented for the purpose of receiving and sending messages by using GSM MODEM along with the executable commands of c#.
Initially connection of GSM modem will must be establish with the usb port of computer or laptop in order to evaluate the program of c#.
SMS application consists of graphical user interface by which we can use the featuresof send SMS, Read SMS, &Delete SMS by using the program of C#.
By using send SMS feature, interface user can enter user Phone number under SIM box and under message field sending text should be entered.
