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.

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.
2
Click Hardware and Sound , then click Phone and
Modem Options . The Phone and Modem Options
dialog box opens.
3
Click the Modems tab, click the modem you want
to adjust, then click Properties .

Click the Modem tab, then adjust the Speaker
volume control.

Options dialog box.
