sending and receiving data using 89c51
Hi to all. I am doing the same project. Have anyone any idea for the same. I am using 8051 for the same. Do anyone have the code for the same.
My idea is, I have connected my telephone to my uc using opto, then after say 5 rings it get connected to land lien & the person on the other side presses the nos. to be displyed on my LCD connected to 8051. Say if someone presses 1 the LCD will display A, for 2 it is B, for 3 it is C & so on... to receive the SMS.
