Motorola V.3600 manual Creating a Command Statement AT

AT Commands

Creating a Command Statement — AT

To create a command statement use the following steps:

1)Type AT. This is the Attention Code telling the unit a command statement follows.

2)Type the command.

3)Press the Enter key to send the command statement to the modem.

An example of a command statement using the dial command (D) follows.

ATD554-1212

This statement can be read as “Attention: Dial 554-1212.”

Another AT command statement example is:

ATZ

This statement can be read as “Attention: execute the Z command.”

After entering a command line the modem returns a response message indicating whether or not the command was accepted or giving the data requested by the command line.

To clear command statements from the buffer you can:

•Turn the modem off,

•Enter AT, or

•Use the DTR reset feature (“Data Terminal Ready — &D” section on page 5-20).

Autobaud

The attention code (AT) is analyzed by the modem to determine the transmission speed, parity, and bits per character used by the DTE. This autobaud process is repeated each time the AT command prefix is sent.

Guidelines for Creating Command Statements

The attention code (AT) may be upper or lower case but not a combination like aT.

•Press the Enter key to execute a command.

•The command buffer can hold 80 characters.

•Use the backspace or delete key to erase the last character.

Even though the initial AT code must be all upper or lower case, characters that follow can be any mix of upper and lower case.
