15

= 15 seconds

 

30

= 30 seconds (default)

 

60

= 1 minute

 

120

Bit 2 = 1:enables on screen echo of AT commands.

 

Bit 2 = 0: disables on screen echo of AT commands.

 

Bit 3 = 0: enables AT responses from the ISU 2x64.

 

Bit 3 = 1: disables AT responses from the ISU 2x64.

 

Bit 4 = 1: enables AT responses to be displayed

 

in text form.

 

Bit 4 = 0: enables AT responses to be displayed in nu-
