AT Commands Protocol & Structure Configuration
The AT commands message flow and structure may be configured by the terminal.
The H24 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
S3=[]
S4=[]
Description
Command line termination character (default setting 0x13).
Response formatting character (default 0x10).
S5=[] Command line editing character (default 0x 8).
E[]
Q[]
V[]
X[]
Command echo (default 0, meaning the H24 does not echo commands).
Result code suppression (default 0, meaning the H24 transmits result
codes).
H24 response format (default 1, meaning verbose format).
Defines CONNECT result code format.
