Modem 34336

• Z —Recall Stored User Profile. The Z command resets the modem and

recalls a profile of the modem configuration settings previously saved

using the &W command. The profile is designated as profile 0 or

profile 1 when it is saved using the &W command.

• , —Pause. A comma causes the modem to pause for 2 seconds (or time

specified in register S8) before processing the next character in a dial

string or command. The Pause command is used to place an outside call

through a PBX switchboard, where 9 must be dialed to gain outside

access—the pause allows time for the dial tone to occur before the

modem dials the number:

AT D9,3331234

Similarly, a comma may be used to cause the Modem to wait for a second

dial tone before beginning to dial a telephone number. Use multiple

commas to increase the pause time.

• ; — Forced Command State. A semicolon placed at the end of a dial

command causes the Modem to return to the command state after

dialing without disconnecting.

The following examples illustrate how the ; command is used:

The first example is a banking transaction. The command AT D333-1234;

dials the bank’s phone number and returns the Modem to the command

state. After the OK prompt is displayed on the DTE, the command AT D

T 0901# is entered. The command transmits the identification number

0901 to the bank, and again returns the Modem to the command state.

An account number and other data may be transmitted in the same way.

The second example illustrates one method of autodialing. Enter a dial

string that ends with a semicolon—for example, AT DT9, 3331234;

During the ring signal or when the call is answered, pick up the phone

and enter AT H. You may then use a telephone connected to the Modem

for voice communication.

• Wait For Silence Before Dialing. The @ command is used to gain access

to a system without a dial tone. It tells the modem to wait for 30 seconds

(or the time specified by register S7) for one or more rings followed by 5

seconds of silence before processing the next symbol in the dial string.
