Section Four - S Registers
Your modem has 24 registers, designated S0
through S33. Table 4-1 shows the registers, their func-
tions,andtheirdefaultvalues.Someregisterscanhave
their values changed by commands. If you use a com-
mandtochangearegistervalue,thecommandremains
in effect until you turn off or reset your modem. Your
modem then reverts to the operating characteristics

Thissectiondescribessomeofthecommonprob-
lemsyoumayencounterwhileusingyourmodem.Ifyou
cannotresolveyourdifficultyafterreadingthischapter,
contact your dealer or vendor for assistance.
Modem does not respond to commands.
1. Make sure the modem is not configured with a
conflictingCOMportandIRQsetting(seeSections
2.2-2.5). As an example, your modem can not be
configuredasCOM1ifanotherdeviceinyoursystem
isalsoconfiguredasCOM1.
2. Makesurethecommunicationsoftwareisconfigured
to“talk”tothemodemonthecorrectCOMportandIRQ
setting (same COM port and IRQ setting as the
modem).Yourcommunicationsoftwaremustknow
whichaddressyourmodemisusinginthesystemin
ordertopassdatatoit.Similarly,IRQsettingsmustbe
set correctly to receive data from the modem.
3. Make sure that your modem is initialized correctly.
Yourmodemmayhavebeeninitializedtonotdisplay
responses. You may factory-reset the modem by
issuing AT&F and pressing ENTER. The factory
defaultallowsthemodemtodisplayresponsesafter
acommandhasbeenexecuted.
4. Make sure the baud rate setting in your software is
setto115200, 57600, 38400, 19200, 14400, 9600,
2400, 1200, or 300 bps. An incorrect baud rate
preventsthemodemfromoperatingproperly.

Modem does not dial.
1. Make sure the modem is connected to a working
phoneline.Replacethemodemwithaworkingphone
to ensure that the phone line is working.
Modem dials but does not connect.
1. Make sure the IRQ setting is identical on both the
modem AND the software. Modem and software
mustbeconfiguredidentically.
2. Makesurethephonelineisworkingproperly.Replace
themodemwitharegularphoneanddialthenumber.
If the line sounds noisy, you may have difficulty
connectingtotheremotedevice.
Modem makes a connection but no data
appears on your screen.
1. The remote system may be waiting to receive your
