AT Commands Protocol & Structure Configuration

The AT commands message flow and structure may be configured by the terminal.

The G24-L can be configured not to follow a command with an echo and/or results code. It can be configured to transmit the results code in either of two ways: Verbose or Numeric. This (and other) configurations can be set using the following commands:

Command	Description
S3=[<value>]	Command line termination character (default setting 0x13).
S4=[<value>]	Response formatting character (default 0x10).
S5=[<value>]	Command line editing character (default 0x 8).
E[<value>]	Command echo (default 0, meaning the G24-L does not echo commands).
Q[<value>]	Result code suppression (default 0, meaning the G24-L transmits result
	codes).
V[<value>]	G24-L response format (default 1, meaning verbose format).
X[<value>]	Defines CONNECT result code format.

The figure below shows the flow and structure configuration commands:
