Using a Custom Modem Initialization String
A custom Modem Initialization String is sometimes required in order to control the behavior of the modem
in special circumstances. While there are many different initialization string possibilities, the most common
one modifies how the modem handles dial tone. Sometimes the modem may be connected to a circuit that
does not provide the US standard 350/440 Hz dial tone, and in this case, you need to tell the modem to
ignore it.
Edit Connection dialog box with "Modem Initialization String" edit box
The extra dialing commands that modify modem behavior should be entered into the "Modem Init:" box in
the Edit Connections menu. If you are "modem init string savvy", you could ignore the "Modem Init:" box
altogether and place the complete dialing command string into the Phone # box. The choice is yours.
As pointed out earlier, a common customer need is the ability to tell the modem to ignore a non-standard
dial tone. For that situation, the most commonly used options are:
X0 - Disables both busy and dial tone detection.
X1 - Disable busy and dial tone detection.
X2 - Disable busy detection, enable dial tone detection.
X3 - Enable busy detection, disable dial tone detection.
X4 - Busy and dial tone detection enabled.
