a number without disconnecting. The semicolon must be placed at the end of the dial

@ WaIt for Quiet Answer Command. ” @ ” causes the modem to look for rings followed by
5 seconds of silence before processing the next symbol in the dialing string. The S7
register value determines the maximum wait time. If quiet answer is detected, the dial
modifiers following the command are executed. If busy is detected, the modem returns
a BUSY result code and goes to the hang-up process, aborting further execution of
commands.

B, C, D, #, and * represent specific tone pairs and, therefore, can be used only when
tone dialing is selected.

W 30 seconds Wait for Dial Tone. W causes the modem to wait up to a specified time for the dial tone

instead of dial tone, the modem returns a BUSY result code and goes on-hook,
abandoning subsequent instructions on the command line.
