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.
