AT COMMAND SET

4-9

P - Set Pulse Dialling

Normally the DPX-213 will automatically sense whether to use tone or pulse dialling.

Using this modifier causes any further digits in the dial string and if ATX3 is set, dial

commands, to be dialled with decadic pulses. Thus, pulse and tone dialling may be mixed

in the same telephone number. The default setting is for check for tone dialling. If ATX4

(check for dial tone) is set, the DPX-213 will dial the first digit of a dial string in tone

mode and recheck for dial tone. If dial tone is still present, the entire number will be

dialled in pulse mode, otherwise, the rest of the number will be dialled in tone mode.

T - Set Tone Dialling

Causes any further digits in the dial string (provided ATX3 is set) or dial commands to be

dialled with DTMF tones. Pulse and tone dialling may be mixed in the same telephone

number. If ATX4 (check for dial tone) is set, the DPX-213 will dial the first digit of a dial

string in tone mode and recheck for dial tone. If dial tone is still present, the entire number

will be dialled in pulse mode, otherwise the rest of the number will be dialled in tone

mode. A 'T' or 'P' command in a dial string will override the automatic tone/pulse selection.

, (comma) - Pause

Causes the modem to wait for the time in register S8 (2 seconds) before continuing.

Sometimes used after dialling the STD codes before dialling the rest of the telephone

number. For example:

ATDn DIAL Stored Number

Parameters : 0 to 9

Default : 0 (act on Number in location zero)

The ATDNn command causes the DPX-213 to go off-hook and dial the number stored in

location n. It is equivalent to typing ATD followed by the valid dialling characters stored in

location n.

ATE Command ECHO

Parameters : 0 or 1

Default : 1 (Echo Enabled)

The ATE command controls the echoing of characters from the DTE in local command

state.

ATE0 - Disable Local Echo.

ATE1 - Enable Local Echo. The modem echoes all characters from the local DTE.
