This confirms that the modem and your computer are
communicating correctly.
To test the telephone line connection, issue the manual answer
command. Type:

an incoming call made from another modem. Thus the high
pitched noise you will hear from the speaker. To abort the
operation, press any key, or select “Disconnect” from the
“Call” menu.
