Lucent Technologies 7400B manual Command Function

APPENDIX A: AT COMMAND SET	DEFINITY Communications System
	7400B Data Module
Page A-6	User’s Guide

Command:	D (Contd.)
S-Register:	Bit 7 of S14 is set to 1.
Example 1:	atd555–1212 [ Enter ]
Example 2:	atds=1 [ Enter ]
Comments:	In example 1, the number 555-1212 is dialed. The hyphen (-) is
	optional and may be used for easier reading of the command line. In
	example 2, the number stored in telephone number location 1 is dialed.
	The maximum length of the ASCII string is 39 characters; the AT
	prefix, the carriage return, and spaces used for readability do not add to
	the character count for the line.
	Note: Other commands should not be issued following the dial
	string until the call is either completed or fails. If anything
	is typed before the call is completed, the call will fail.

Command:	E
Function:	Turn the command echo on or off.
Type:	configuration
Arguments:	No argument or an argument of 0 disables echo and an argument of 1
	enables echo. The factory-default is 1.
S-Register:	Bit 1 of S14 is set according to the argument of the command.
Example:	ate1 [ Enter ]
Comments:	Typically, for a display terminal operating in full-duplex mode, use the
	1 argument if you wish to see the AT commands on the screen as you
	type them. If your display terminal is operating in half-duplex mode,
	use the 0 argument (the 1 argument would cause characters typed to
	appear on the screen like tthhiiss).
