6.2 Syntax Of The Standard AT Commands
Modem guideline V.25 ter is applicable as regards the time sequence of interface com-
mands. The AT standard is a line-oriented command language. Each command is made
up of three elements: the prefix, the body and the termination character.
The prefix always consists of the letters AT, except the A/ command.
The body is consists of a name and, if applicable, of associated values. In case an associ-
ated value is optional, it is marked by square brackets ([...])
The default termination character is <CR> (= 0x0D).
Commands may be combined in the same command line. Spaces between the individual
bodies are ignored. The commands can be classified as:
• basic command set
• extended command set (beginning with “+“ or “^“)
Commands are acknowledged with "OK" or "ERROR". A command currently being proc-
essed is interrupted by each subsequent incoming character. Consequently, the next
command must wait until acknowledgment has been received as otherwise the current
command will be canceled.
