note didier <br> I guess my English is worst than I was thinking ;)<br> <br> I have two Win32 machines, each with a modem.<br> The first one should dial the phone number of the second machine.<br> I know how to use the Win32::Serialport to do that, and I know how to exchange data through a normal phone when you know the protocole at server side.<br> <br> I just need to know how the second machine can listen at the serial port and get the line if called.<br> <br> This is not "socket programmming". But handle socket and the modem at the same time has been done here before, see [http://www.perlmonks.org/?node_id=353466]<br> <br> Anyway, thank for your time [splinky]<br> <br> 497150 497266
