Hi, i have a question about modem 56k.Please dont tell me..google it.. i made it about 32159127579 times and didnt find anwser to my question. :p.
so, if i use an old 56k modem with rs232, do i only have to tell the modem to call a number (with AT command), and send my data on the tx pin of the rs232 and get them on the other modem on the Rx pin? Because everyone says oh its easy. but i just want to know how. yeah i understand how the modem work but will it work if i made it. :p
is this easy as i think? or i cannot do that?
arduino -> serial data -> tx pin of the modem -> modem modulate data in frequency -> phone line -> (other modem get the data) modem demodulate the signal - > rx pin of the modem -> second arduino.
thanks a lot.
