A friend in my local astronomical society is having modem problems. He is unable to obtain a connection as the modem refuses to dial out. Last night I suggested that he went into Internet options/ connections to see if the setting had changed to "never dial a connection" as that used to happen a lot with 2 of my previous machines, preventing them from dialling out. However, the setting is "always dial a connection".
He has bought a new phone cable to connect the modem to the phone socket but to no avail. He's opened up the computer and checked that the modem connections are sound so he now thinks he may have a faulty modem. Before he changes it, can anyone think of any other reason for his problem, or any other test he could perform?
