Escape Code Recognition

Allows the recognition of the escape character sequence to be enabled or disabled.

The Escape code is defined in S-Register 2 (default is a +); the escape guard time is defined in
S-Register 12 (default is 50 units; where each unit is 1/50 sec.).

If S-Register 12 is set to 0 the DART escape sequence approximates the Hayes escape sequence.

The escape function can be disabled (not recommended) only if the escape with the &Dn function is
activated.

NOTE:
Setting S-Register 12 = 0 should be avoided if binary data is being transferred, since there is no
preceding or following guard times as the Hayes method provides and an unwanted escape is
possible.

Format:

AT&E0

Recognition Disabled

AT&E1

Enable escape recognition and pass the escape characters onto the network
(default)

AT&E2

Enable escape recognition and filter the escape characters from the output data
stream when the escape sequence is valid

Result codes:

Valid argument

Invalid argument

Restore Factory Defaults

Resets the DART active profile and S-Registers to the factory default settings. It does not reset the
NEI list, SLIP address, MAS address, dial directory, or \J, \N, or *A settings.

This command restores the default settings temporarily. In order to make them permanent, follow the
AT&F command with an AT&W command.
