A version of the basic syntax is:
AT<command><parameter>
Extended Syntax Command
AT+<command>= [<parameter>]
AT*<command>=[<parameter>]
EXAMPLE! - AT+CFUN=0<CR> (powers down the modem)
If several values are included in the command, they are separated
by commas. It is also possible to enter commands with no values.
Additional commands may follow an extended syntax command on the same
command line if a semicolon (; IRA 3B) is inserted after the preceeding
extended command as a separator.
Read Command Syntax
The read command is used to check the current values of
parameters. Type ‘?’, after the command line:
AT+<command>?
AT*<command>?
AT<command>?
Example!_ AT+CSCS?<CR> (show current character set)
<CR>“IRA”<CR>(information text response)
<CR>OK<CR>(final result code response)
Test Command Syntax
The test command is used to test whether the command has been
implemented or to give information about the type of subparameters it
contains. Type ‘?’, after the command line:
AT+<command>=?
AT*<command>=?
Example!_ AT+CPAS=?<CR> (shows supported values for the
response parameters)
<CR>CPAS: (0, 3, 4, 129, 130, 131)<CR> (supported values)
<CR>OK<CR> (final result code)
