You need to reset the modem.

These commands can ALL be executed by simply running
the cat command, such as is shown here:
cat > /dev/ttyxx     #Substitute the device name for ttyxx)
ATZ                     # reset the modem to default state]
ATH0                    # go on hook (hang up)]
ATH1                    # o off hook]
ATDT 1234567            # dial 123-4567 using touch-tone (DTMF)]
^D                      # Ctrl-D to end cat command


Once you get everything worked out as to what you need
to do before running wvdial again, you can put it into
a script, like this

You could save this script "redial" and then make it executable.

You can call it as either:

$ redial                # use default tty device.

or

$ redial /dev/ttyS0     # overrides default tty device]]


        #!/bin/bash
        # Shell script to reset modem
        # and then run wvdial again

        MODEM=/dev/ttyxx        # Modem's device here
        
        if [["$1" != "" ]]  # test for cmd line argument
        then
                MODEM = $1      # set modem to cmd line arg.
        fi

        cat > $MODEM << end_of_commands
        ATZ
        ATH0
        ATH1
        end_of_commands


        wvdial

        # End of script.
