I need to connect to a modem of a mobile phone via the serial port of the 8052.
I use the 9600 bauds, 8 bits of data, no parity and one stop bit.
I simply send AT command to the modem to dial the number of another mobile phone.
Do I have to send some inicialization commands, before dialing the number?
Do I have t o wai for any response from the modem?

Thanks in advance
