Landline Modems
The modem dials and receives an answer but does not establish a connection
• You may have incorrect parameters selected for your application to talk with the remote modem. Refer to the
online Help for your application.
• You may need to adjust your modem’s baud rate or protocol selection.
Communications programs such as HyperTerminal or Procomm Plus don’t seem to work
or they lock Windows
• If you are using the internal modem, be sure to specify the proper communications port.
• When you first try to use HyperTerminal or similar application, the system responds with a message asking if
you want to install the modem. Answer “Yes” to this question and follow the instructions on the screen to
install it.
The modem dials and the answering modem generates tone, but our modem does not begin
the training sequence to establish a connection
Although the problem may appear to originate from the computer, the source of the problem is the answering
modem.
• Try setting up the answering modem to generate the correct V.22 tone, which can usually be done by sending
an AT command to the modem.
• Add %!1300AO to the initialization string. If used, this command must be sent immediately before the
command to dial the desired phone number and sent again before re-dialing the number since the modem will
default to the original setting at the end of the session.
