AT Commands
5-3
You may use numbers 0~9 in all dial strings. You may also use spaces,
hyphens, parentheses, or any other punctuation except the dial
modifiers to make the command line easier to read.
5.4
Tone or Pulse Dialing (T or P)
To tone or pulse dial a number sequence, insert a
T
or
P
between the
dial command (D) and the phone number. The modem prepares for
tone dialing.
If you have used P in the last dial string, you only need
to enter a T in the dial string.
For example:
ATDT(or P)12345678
5.5 Pause
(,)
Inserting a Pause command in the dial string inserts either a 2-second
pause or the value in status register S8 in the dialing sequence.
For example:
ATDP,12345678
