Initialization (AT Command Interface)
In the GSM vocabulary, a call from GSM mobile to the PSTN is called a "mobile-originated call"
or "outgoing call". A call from the fixed network to a GSM mobile is called a "mobile-
terminated call" or "incoming call."
In the following examples, “Entry” refers to the application. The following convention
describes the direction of the data exchange:
l
The data exchange from the customer application to the module is designated as: Entry
l
The data exchange from the module to the customer application is designated as:
Response
Note: With the exception of the +++ command (Online Escape Sequence), all
commands must be preceded by the AT attention code (or command prefix) and
terminated by pressing the <CR> character.
In the following examples, the <CR> and <CR><LF> are intentionally omitted for
clarity and space.
