The modem is noisy when it dials and connects
When your modem tries to connect to another modem, it begins handshaking.
Handshaking is a digital “getting acquainted” conversation between the two
modems that establishes connection speeds and communication protocols.
You may hear unusual handshaking sounds when the modems first connect. If
the handshaking sounds are too loud, you can turn down the modem volume.
To turn down the modem volume:
1 Click Start, then click Control Panel. The Control Panel window
opens. If your Control Panel is in Category View, click Printers and
Other Hardware.
2 Click/Double-click the Phone and Modem Options icon, then click
the Modems tab.
3 Click the modem you want to adjust, then click Properties.
4 Click the Modem tab, then adjust the Speaker volume control.
