NAME

gsmsmsd - SMS message reception daemon

SYNOPSIS

gsmsmsd [ -a action ] [ --action action ] [ -b baudrate ] [ --baudrate baudrate ] [ -c concatenatedID ] [ --concatenate concatenatedID ] [ -C service centre address ] [ --sca service centre address ] [ -d device ] [ --device device ] [ -D ] [ --direct ] [ -f ] [ --flush ] [ -h ] [ --help ] [ -I init string ] [ --init init string ] [ -r ] [ --requeststat ] [ -s spool directory ] [ --spool spool directory ] [ -t SMS store name ] [ --store SMS store name ] [ -v ] [ --version ] [ -X ] [ --xonxoff ] { sms_type }

DESCRIPTION

gsmsmsd reads new incoming SMS from the mobile phone and dispatches them to a user-defined action. Additionally it can send SMS message that it reads from a spooldir.

gsmsmsd attaches itself to the device given on the command line (usually an GSM modem) using the specified baudrate and waits for incoming SMS messages. If no device is given, the device /dev/mobilephone is used. If no baudrate is given, a default baud rate of 38400 is used.

If no action is given, the SMS message is printed to the standard output. If an action is specified the action is excecuted using the shell and the SMS message is written to the standard input of the action.

gsmsmsd needs one empty storage slot for SMS messages in the mobile phone, otherwise SMS reception will not work. The SMS store to use for temporary storage of incoming SMS can be selected using the --store option, otherwise the ME default store is used.

To terminate gsmsmsd cleanly (without losing SMS messages) one should send either SIGINT (CTRL-C on the command line) or SIGTERM to the process.

Error messages are printed to the standard error output. If the program terminates on error the error code 1 is returned.

sms_type may be any combination of:

sms, no_sms

Controls reception of normal SMS messages.

cb, no_cb

Controls reception of cell broadcast messages.

stat, no_stat

Controls reception of status reports.

The default is sms, cb, and stat.

OPTIONS

-a action, --action action

The action to execute for each incoming SMS message. If no action is given the SMS is written to the standard output.

-b baudrate, --baudrate baudrate

The baud rate to use.

-c concatenatedID, --concatenate concatenatedID

If an ID is given, large SMSs are split into several, concatenated SMSs. All SMSs have the same ID and are numbered consecutively so that the receiving phone can assemble them in the correct order. IDs must be in the range 0..255. This number is increased by one for every outgoing concatenated SMS and wraps around after 255. Not all receiving phones will support concatenated SMSs (and display them as separate SMSs), since all the numbering and ID information is carried in the user data header element at the beginning of the SMS user data. This information may show up as garbage in such phones.

-C service centre address, --sca service centre address

Sets the service centre address to use for all SUBMIT SMSs (may not work with some phones).

-d device, --device device

The device to which the GSM modem is connected. The default is /dev/mobilephone.

-D, --direct

Enables direct routing of incoming SMS messages to the TE. This is not supported by many mobile phone/GSM modem combinations. Therefore, the default is to store incoming SMS temporarily before processing them in the indicated store.

-f, --flush

This option causes gsmsmsd to flush (ie. read and erase) existing SMS messages from the SMS store selected by the --store option. The action given by the --action option is executed on each of the flushed SMS. This option should be used to ensure that enough space is available in the SMS store for temporary storage of incoming SMS, otherwise incoming SMS might be ignored silently by the ME.

-h, --help

Prints an option summary.

-I init string, --init init string

Initialization string to send to the TA (default: "E0"). Note that the sequence "ATZ" is sent first.

-r, --requeststat

Request status reports for sent SMS. Note: This option only makes sense if the phone supports routing of status reports to the TE. Otherwise the status reports might show on the phone's display or get lost.

-s spool directory, --spool spool directory

This option sets the spool directory where gsmsmsd expects SMS messages to send. The format of SMS files is very simple: The first line contains the phone number of the recipient. Everything else after the first line is interpreted as the SMS text. Please refer to gsmsendsms(1) for details on the SMS text character set and maximum length. gsmsmsd polls the spool directory every 5 seconds. Sent SMS message files are removed.

-t SMS store name, --store SMS store name

The name of the SMS store to read from (for the --flush option) or write to (for temporary SMS storage). This option must be must be used in conjunction with the --flush option. If this option is omitted the ME uses it's default SMS store for temporary storage of incoming SMS. A commonly available message store is "SM" (SIM card).

-v, --version

Prints the program version.

-X, --xonxoff

Uses software handshaking (XON/XOFF) for accessing the device.

EXAMPLES

The following invocation of gsmsmsd sends each incoming SMS message as a mail to the user "smsadmin":

 gsmsmsd -d /dev/ttyS2 -b 19200 -a "mail smsadmin"
 

This is the format of SMS deliver messages as output from gsmsmsd:

 ----------------------------------------------------------------
 Message type: SMS-DELIVER
 SC address: '491710762100'
 More messages to send: 1
 Reply path: 0
 User data header indicator: 0
 Status report indication: 0
 Originating address: '01805000102'
 Protocol identifier: 0x39
 Data coding scheme: default alphabet
 SC timestamp: 17.12.98 14:10:55(+0100)
 User data length: 159
 User data header: 0x
 User data: 'Nicht vergessen! Die XtraWeihnachtsverlosung lauft
 noch bis zum 24.12. Nutzen Sie jetzt Ihre Gewinnchance und faxen
 Sie Ihren Teiln.-Gutschein an 0180/5000 056'
 ----------------------------------------------------------------
 

This is the format of SMS status report messages as output from gsmsmsd:

 ----------------------------------------------------------------
 Message type: SMS-STATUS-REPORT
 SC address: ''
 More messages to send: 0
 Status report qualifier: 0
 Message reference: 0
 Recipient address: ''
 SC timestamp: 00.00.00 00:00:00(+0000)
 Discharge time: 00.00.00 00:00:00(+0000)
 Status: 0x0 'Short message received by the SME'
 ----------------------------------------------------------------
 

The following invocation of gsmsmsd flushes all existing messages from the "SM" SMS store and looks in the "/tmp/spooldir" directory for SMS to send:

 gsmsmsd -d /dev/ttyS2 --spool /tmp/spooldir -f --store sm \
 --action 'mail smsadmin'
 

FILES

/dev/mobilephone

Default mobile phone device.

BUGS

Cell broadcast SMS message reception has not been tested, but it has been enabled in the gsmsmsd daemon.

The mobile phone device is blocked when the gsmsmsd daemon is running, ie. it cannot be used for data transfer or from the other programs of this suite (gsmpb, gsmsms).

Report bugs to software@pxh.de. Include a complete, self-contained example that will allow the bug to be reproduced, and say which version of gsmsmsd you are using.
