Can anyone help me with some PHP-code that explains how I can send commands to a modem as well as recieving the reply from the modem.
I've searched the net but couldn't find any real useful info on it. php.net only mentions very little that you can use fopen("/dev/modem"), but I still lack how to get the response back.
I am not looking for system calls within PHP if it's possible to do it another way.
Thanks in advance, Djarnis
