2100EU AT Command Set
Introduction
AT Commands are for the the Information Service
Department, solely to customize specific configurations
for your system. Changing these commands would be
unusual and outside normal operation.
AT commands may be entered via a terminal program,
such as Procomm or Hyperterminal. (Settings 57600, N,
8,1)
Most commands can be combined on one line, although
some must be on a separate AT command line, or the last
command on an AT command line
(*1!N1=, *1!N2=, and ATD). Commands are executed
left to right on the line. If there is an error in a command
in the middle of a line, the commands to the left of it will
have been executed.
If the command consists solely of a letter followed by a
number (e.g. Qn), omitting the number in place of the n is
the same as specifying 0 (For example, ATQ is the same
as ATQ0). Also, following the letter with a question
mark will display the current value for the configuration
parameter (For example, ATE? will display the current
value for the local echo configuration parameter).
For commands that use the equal sign to assign a value to
a parameter, a value must be specified. ATS0= is an
improper command; the value does not default to zero.
To display the value of the parameter configured by such
a command, either replace the equal sign with a question
mark or place a question mark after the equal sign (For
example, ATS0? or ATS0=? will both display the value of
the auto answer configuration parameter).
