Adding a Pause Character

seconds between the required DTMF digits.

want to send your password as DTMF tones
with a ’p’ character between each digit, the
string should be sent as 1p2p3p4.)

string within the same memory location as the ac-
cess phone number by storing a wait character be-

acter, see Automatic Dialing on page 38.
