I have a new (to me) 760C, running Win95, with the MWave modem. The modem works fine on a conventional analog line such as at my home, but I m having difficulty with it at work. I have an analog line, coming from an SRX pbx system, and the MWave modem will not recognize the initial dial tone. The line has a higher pitched dial tone when you first go off hook. After a 9 is dialed, to reach an outside line, the dialtone drops to the conventional tone. The MWave modem will not dial any digits that are entered, as it does not recognize the initial dial tone as being valid. I only get an error message saying that no dialtone was detected, and to ensure the modem is plugged in . . . yada, yada, yada. I normally use a Hayes Optima 288 PCMCIA, and a USR Courier on this same line without any grief. I have looked through the online documentation for the MWave, and I cannot find any AT command settings that will force the modem to dial the initial 9 to get the conventional tone, or to just ignore the tone, an dial blindly. I have upgraded to all the latestbios and drivers, from the IBM web site, for MWave, and everything else. I have also applied Service Pack 1, and all the Win95 patches eleased since service pack 1, as posted on the Microsoft Win95 web site. None of these upgrades affected the MWave modem's ability to detect my pbx's dial tone, although they did solve another anomaly I was experiencing with dial up networking not remembering my password. Any input into solving this one is greatly appreciated. -Tony Staples tstaples@sprintmail.com <---NOTE: NEW ADDRESS
