Section Four
@ Causes the modem to listen for 5 seconds of silence. If a 5 second
silence has not been detected within the period specified in S7
(default = 30 seconds), the modem disconnects and returns the NO
ANSWER result code. If it detects a busy signal, it returns a BUSY
result code. If the 5 seconds of silence is detected, then the modem
continues dialling the dial string.
W Wait For Dial Tone Before Dialling. Causes the modem to wait for a
dial tone up to the period of time specified in register S7 (default = 30
seconds) before dialling the numbers that follow. If the modem
detects a dial tone before the given time delay, it continues to dial.
Otherwise, it goes on-hook.
, Pause During Dial. Inserted between digits in a dial string. Causes
the modem to pause for the value given by register S8 (default = 2
seconds), before dialling the next digit. This delay can be used in
place of the "Wait For Dial Tone Before Dialling", but is not as
sophisticated.
; Return To Command Mode After Dialling. Added to the end of a dial
string. Causes the modem to remain in the command mode after it
dials the digits proceeding the command. This allows the user to
issue additional dial commands or dial strings without overflowing
the command buffer. The modem looks for the carrier after the final
dial command is issued. The Command ATHn aborts this command.
^ Turn On Calling Tone. Turns on the periodic 1300 Hz calling tone if
originating the call. Calling tone is enabled only on a call-by-call
basis.
S=n Dial Stored Number. Follows the dial command string. Causes the
modem to dial a telephone number previously stored in directory
location n using &Zn command.
If ATD is entered without parameters, the modem goes off-hook and
waits for a carrier; if the handshake is not completed within the specified
time by register S7 (default = 30 seconds), the modem goes on-hook.
The Dial command will be aborted in progress upon receipt of any
character before completion of the handshake.
