2.8 UsingYourModem
The communication software included with your
modem product provides a user friendly interface to
accessthefax,voiceanddatafunctionsofyourmodem.
This software should be sufficient for all of your
communicationneeds .Theremaybetimeswhenyou
needtoaccessthemodemmanuallyviamodemcom-

modem command set before manually accessing the
modem.Youmaywanttoreadthesoftwaremanualfirst,
however, as the software may already provide a user
friendlymethodofaccessingthefunctionsyouneed(i.e.
dialingoransweringcalls).
2.9 Where To Go From Here
Youshouldfamiliarizeyourselfwiththefunctions
availablefromtheincludedsoftwarebyreadingitsmanual.
You will be accessing most, if not all, of the modem's
functionsfromthis software.Youmayalsouseanyother
commerciallyavailable communicationsoftwarewiththe
