Dial Modifiers
B-3
Dial Modifier: P
Function: Request to make a voice call.
S-Register: S6
Example: ATDP9, 9570000
Comments: The purpose of the P dial modifier is to signal the 8400B
Plus Data Module to dial the number that follows as a
voice call. When entered immediately after the D in a
dial command and/or as the first character in a stored
number, the 8400B Plus Data Module will place a voice
call. When the P is omitted or the T is used, the 8400B
Plus Data Module will place a data call. When the P is
entered after the D and a stored number is dialed, a
voice call is made even if the first character of a stored
number is the T dial modifier. The blind dial S-register
(S6) is used to delay between going off-hook and
dialing the first digit.
