Figure 17: Welcome message in HTerm with Windows 7
Welcome message is hardware/software specific!
The welcome message may not appear, depending on the hardware and software
being used. In this case, use an AT command to test the connection, e.g. the
welcome message is output again via “AT INFO.”

Basic Structure of an AT Command
•
Every AT command consists of the command and any additional parameters
separated by spaces.
•
AT commands that affect device settings use an equal sign
=
between the
command and parameter.
•
AT commands for reading device settings or information can optionally
contain a question mark
?
at the end of the command.
•
The command is concluded with the character for “carriage return.” This
character is 0x0d or decimal 13 from the ASCII code. This character is
transmitted automatically when using the PC software HyperTerminal, for
example, when you press the Enter key.
