4.0 CONFIGURATION
Before attempting to configure or operate the Model 2190, it is
important to know how the unit will handle command entry. This section
provides command guidelines, AT command set, dial codes, sub para-
meter definitions, fax commands, and voice commands.
4.1 COMMAND GUIDELINES
• All commands must be preceded by "AT" (ATtention code) except
for the “A/” command and "+++" escape command.
• AT commands are not case sensitive and can be entered in lower
case or uppercase characters.
• AT commands cannot be deleted by the backspace key or by the
delete key.
• The Attention Code is used by the modem to determine the speed
and data format of the in coming data from the DTE.
• More than one command can be entered in one command line
and may be separated by space for readability.
• The command line can NOT exceed 40 characters excluding the
attention code and must be ended by the ASCII character speci-
fied by S register 3.
• The default of the S register 3 is the decimal 13 -- "Carriage
Return"
• A line without carriage return will be ignored.
• Commands following the AT are processed after receiving the
"Carriage Return" character, and the space added for readability
will be ignored.
• Any parameters following the AT command that were ignored will
be treated as equal to 0.
