Quick Tips when issuing AT Commands • The ENTER or RETURN key must be pressed to execute a command. • Multiple AT commands can be combined into one line. For example, AT&D2 and AT&N0 can be combined into one line AT&D3&N0. The Comet processes commands from left to right.
AT Command Set/Type Example Fax and Voice AT+ commands AT+FCLASS=2 S-Register command ATS0=1 S-Register inquiry command ATS0? You may browse the lists of available commands for each command set by using the on-line help commands: AT$, AT*$, and AT&$. Modem Result Codes When you execute or try to execute an AT command, your modem sends a result code to let you know whether the command was executed.
For example, to have your modem auto-answer an incoming call after two rings, set S-register 0 to 2. Be sure the n value is between 1 and 255. If n is set to 0, your modem will not answer incoming calls. Non-Volatile Memory The Comet has memory set aside for storing user information such as frequently used phone numbers and default command settings.
n=3 views factory settings AT&Wn Stores the current settings in user profile ‘n’; n=0 to 1 ATZn Resets the current settings with the settings in profile ‘n’, n=0 to 1 Resets the current settings with the factory settings, n=2 Default Modem Settings for PC’s The Comet factory settings are configured for operation with PC type computers and communications software.

S4 - Line Feed Character Sets the character recognized as a line feed. Pertains to asynchronous operation only. The Line Feed control character is output after the Carriage Return control character if verbose result codes are used. S5 - Backspace Character Sets the character recognized as a backspace.
