AT command result codes
Each time an AT command line is executed, the router responds with a result code to indicate
whether the command was successful. If all commands entered on the line are valid, the OK result
code will be issued. If any command on the line is invalid, the ERROR result code will be issued.
Result codes may take the form of an English word or phrase (verbose code) or an equivalent
number (numeric code), depending on the setting of the ATV command. The default is to use
verbose codes.
Use the
ATV0 command to select numeric codes if required. The results from the text based
commands can be numeric or verbose. The tables lists the result codes:
S registers
S (Special) registers are registers in the router for storing certain types of configuration information.
They are essentially a legacy feature included to provide compatibility with software that was
originally designed to interact with modems. See S register definitions for a list of S registers.
