13.8 AT+CMGW Write Short Messages to Memory
The execute and write commands transmit a short message (either SMS-DELIVER or SMS-SUBMIT) from TE
to memory storage <mem2>. Memory location <index> of the stored message is returned. Message status will
be set to 'stored unsent' unless otherwise given in parameter <stat>.
After invoking the execute or write command wait for the prompt ">" and then start to write the message. To save
the message simply enter
<CTRL-Z>. After the prompt a timer will be started to observe the input.
To abort writing use
<ESC>. Abortion is acknowledged with "OK", though the message will not be saved.
Syntax
Notes
• If writing fails, for example, if a message is too long, the result code depends on the current setting of the
AT^SM20 command:
If the AT^SM20 <CmgwMode>=1 (factory default) any failure to send a message is responded with "OK". Users
should be aware, that despite the "OK" response, the message will not be written to the selected SMS stor-
age.
If the AT^SM20 <CmgwMode> equals 0 any failure to write a message is responded with "ERROR".
