+CMGF=<n>

+CMGF?

Select SMS message format

Specifies the input and output format of messages to use. <n> indicates the

format of messages used with send, list, read and write commands and

unsolicited result codes resulting from received messages.

There are two available formats for text messages:

• <n>=0 specifies PDU (Protocol Description Unit) mode, in which the

complete SMS message, including all header information, is passed as a

binary string..

• <n>=1 specifies text mode, where the headers and body of the messages

are given as separate parameters.

Text mode is an encoding of the bit stream represented by PDU mode. See

+CMGC (page 77) for information on sending messages.

+CMGF? returns the current setting.

+CMGL

[=<status>]

List SMS messages

Lists messages of the specified <status> from the message store. If <status> is

omitted, the command lists all messages (same as <status>=4).

The format of the returned messages depends on whether the modem has been

set to PDU or text mode (see +CMGF, page 78):

• In PDU mode, returned messages appear in the form:

+CMGL: <index>,<status>,<alpha>,

+CMGL: <index>,<status>,<alpha>,

etc.

• In text mode, returned messages appear in the form:

+CMGL: <index>,<stat>,<oa/da>,<alpha>,

+CMGL: <index>,<stat>,<oa/da>,<alpha>,

[etc.]
