hi,sorry for my English i want to interface gsm modem with 8051 using serial communication , but first i want to know if (GPRS/GSM-Modem SINAUT MD720-3) must connect first to rs232 circuit or it has already inside it a rs232 circuit because on websites i read that not all modems needs to rs232 circuit and , please help me to know how to connect i
its just connecting to serial port and configuring the bauud rate properly. You dont need any interfacing as the module and your 8051 board will have MAX 232 in it. The zigbee module should have a max232. check if it is there or not. If it is there then directly you can connect.

What modem are you talking about? Is it Benq m22 or m23? They are almost the same. I have used this modem before many times. You do not need to convert any signal if your going to use it with a microcontroller. You only need max232 level converter if your going to connect it to a computer. I recommend you to try to communicate using a computer f
