5.2. AT Commandes
A command starts with the two ASCII characters: "AT", followed by one or more characters and data (see C below for the syntax of AT com-
mands available on the modem).
Each command should end with a "CR" or "CR" "LF", the two possibilities are accepted. (CR signifies: Carriage Return, LF signifies: Line Feed)
On receipt of a command the modem returns:
• "the data"<cr><lf>, for a reading command, type ATS<n> ? , AT/S or AT/V.
• "O" <cr><lf>, for all other types of commands if it is accepted.
• "E" <cr><lf>, if it refuses the command because of a syntax error, unknown command, unknown register, invalid parameter, etc.
• "W"<cr><lf>, if it refuses the command because the configuration requested is not authorised.
• "CM" <cr><lf>, if it accepts entry into the command mode
