Re: Any V.90 modem experts around?
If the line interface has failed, then the modem would still appear 100% good on the PC side.
My stock test is to connect to the modem as a COM port with terminal software.
If it cannot dial and ring an ordinary number by TONE (ATDTnumber), try PULSE (ATDPnumber) - if that succeeds, then the line isolating transformer is blown (or a microfuse).
