&E

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.

Restore Factory Defaults

 

Resets the DART active profile and S-Registers to the factory default settings. It does not reset the

This command restores the default settings temporarily. In order to make them permanent, follow the

 

AT&F command with an AT&W command.
