Modem Answers

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."
