! hook flash
The ! dial modifier issues a hook flash signal — the modem hangs up for a short period.
Hook flashes are commonly used with PABXs to transfer calls.
For example:
To dial 0, hook flash and then dial 12345:
•Type: ATD0!12345 <E>
☞UK Modems. Use of the hook flash is not allowed in the United Kingdom. SRegister 29 sets the duration of the hook flash.
S=n dial stored phone number n
The modem allows you to store phone numbers in
For example:
To dial the stored number two:
•Type ATDS=2 <E>
W wait for dial tone
The W modifier causes the modem to wait for a dial tone before dialling. If the modem does not detect a dial tone within 30 seconds, it returns a message of NO DIALTONE, hangs up and returns to local command state.
You can change the dial tone waiting period from the default period of 30 seconds by changing the value in S Register 7.
☞When using the W modifier, the length of time your modem waits for a dial tone is determined by the value contained in S Register 7 (Wait for Carrier) and not the value in S Register 6 (Wait for Dial Tone).
☞UK Modems. Setting S Register 7 with a value above 58 may invalidate the approval of your modem. S Register 7 must be set to 20 before issuing the W dial modifier.
