18 Sportster Winmodem 33600 & x2/56K - User's manual
Remarks on Using the Modem
Remember the Following Points When Using the
Modem:
• The modem might not work with all modular
telephone sets. Specifically, you must not use the
modem with multi-line telephone sets, sets with
indicator lights or line selection buttons.
• Some voice mail message systems use a specific
tone to indicate that a voice message has been
received. The modem will not be able to dial as long as
this signal is on the line. Listen to the waiting
messages in order to get the normal dial tone back
so that the modem can dial.
• The modem has an automatic speed reduction
function. This means that it automatically reduces its
data transmission speed in order to match the speed
of the remote modem. This also means that it may
take the modem up to 30 seconds to establish
communications with a slower modem.
• A comma (,) in the dialed number causes a pause
during dialing. You can insert multiple commas in the
command line in order to obtain a longer pause.
• The modem must detect a carrier within a specific
time interval, otherwise it will display the message ‘NO
CARRIER’ or ‘NO ANSWER’. You can increase this
interval (in seconds) by going into the terminal mode of
the communications application and typing in:
$76 >YDOXH@
NOTE: This
value
must be between 1 and 255 seconds (refer to
the AT command table for further details). The range of
acceptable values is country-dependent.
