Modem Answers
Incoming Calls
If the modem has the AA LED on and DTR LED on, it
will answer all incoming calls. To disable this feature,
set S-Register 0 to 0 and write it to memory. Type
ATS0=0&W<ENTER>
Modem Does Not
Dial
If your DTE displays the NO DIALTONE message, the
modem is not receiving dial tone.
1. Connect a telephone to the back of the modem,
plugging the modular jack into the connector labeled
“PHONE." For the Z34-PL, plug the phone line into
a telephone to check dialtone.
2. Lift the telephone handset. If dial tone is not
present, you probably have a faulty line. Call the
telephone company.
3. If you hear dial tone but the modem does not dial,
change the X command setting from X4 to X1, since
you probably have a nonstandard dial tone.
Modem Dials But
Cannot
Communicate
If the modem dials a telephone number but does not
establish a communication link, something may be
wrong with the remote modem. Refer to the section
entitled "Modem Fails to Handshake."
