Flash. The modem is switched off line during the time set in
register S29.
W
Wait for a dialling tone. The modem waits for a dialling tone
before the requested number is dialled. If no dialling tone is
detected within the time specified in register S6, the modem is
switched off line and you will see the error message "NO
DIALTONE".
@
Wait for silence: The modem waits for silence on the line for at
least 5 seconds before the next dial command is carried out. If
the modem does not detect that 5-second silence during the
time specified in register S7, dialling is interrupted and you will
see the error message "NO ANSWER". If detection of the
engaged tone is switched on, you will get the message
"BUSY". If the modem detects an answer tone before the
waiting time has expired, the connection will be established.
,
Dial pause: the modem pauses during the time set in register
S8 before the next number is dialled.
L
Repeat last number: the modem repeats the last number
dialled.
;
Return to command mode: this command after entry of the
telephone number will return the
Tornado
to command mode
after the commands before the character ';' have been
processed. You can then enter extra AT commands while the
modem is on line. The extra AT commands may also be
entered on the original command line after the character ';'.
The
Tornado
only continues dialling if an extra command
without the character ';' is entered. You can then interrupt the
dialling with the ATH command.
