I'm trying to install MS Fax preview 2 for NT on a TP760ED. The driver is supposed to work with class 1 fax devices. During the installation, the internal Mwave fax/modem is not recognized. Does anyone know if Mwave is class 1 compliant ... or 'only' class 2, or a clue to solve this problem? BTW an external (Boca) fax/modem is perfectly recognized by the fax services. Regards, Alain
