Text messages
An SMS file is a text file that contains the message and a header. You have to store all SM you want to send in these files in the outgoing directory. The filename does not matter but it has to be unique. You may use the mktemp command to generate unique filenames.
Easy example:
To: 491721234567 Hello, this is the sms. |
Write the phone number in international format without the leading +. When you like to send a message to a short number (for example to order a ringtone), then preceed it with an "s".
More complex example:
From: Stefan To: 491721234567 Flash: yes Hello Stefan, how are you? |
You can add as many header lines, as you like. When the program finds an unknown header, it simply ignores that line. You can use the following header lines:
From | Senders name or phone number. This field has currently no function to the software. | ||||||
To | Receivers phone number in international format without the leading +. When you like to send a message to a short number (for example to order a ringtone), then preceed it with an "s". | ||||||
Flash | Boolean value. If yes, then the message appears directly on the phones display. Most phones support this feature, but not all. | ||||||
Alphabet | Tells the program what character set is used in this sms file. Possible values are
The program checks only the first 3 characters of that line, therefore keywords like ISO-8859-15 or UCS-2 will also work fine. |
Note: In case of boolean values you can use true, yes, on or 1 for positive values. All other words are interpreted as negative.
Binary SMS, Operator Logos, Ringtones
If the message has binary content it will be sent as 8 Bit. The binary data begins after the empty line and goes until end of file. Binary messages are limited to 140 bytes.
Example:
To: 491721234567 Alphabet: binary UDH: true gs2389gnsakj92fs2ujtiegbhewqu2ir9jsdgufh3gjeruqgh87zt243htgerugsqh 3gert324543t43g5jwht934zt743gfjsbfjwr793thruewgfh7328hgtwhg87324hf hwer32873gert324543t43g5jwht934zt743g |
You can use the following header lines:
From | Senders name or phone number. This field has currently no function to the software. |
To | Senders name or phone number. This field has currently no function to the software. |
Alphabet | binary |
Binary | true, whis means the same as Alphabet: binary. This is for compatibility to older versions. |
UDH | Boolean value.Set it to yes, if the data contains an User Data Header (see GSM 03.38 specification). The default is yes, because most binary messages contain an UDH. |
Received messages
The received SMS are stored in the same format as described above but they have some additional header lines. For example:
From: 491721234567 From_SMSC: 491722270333 Sent: 00-02-21 22:26:23 Received: 00-02-21 22:26:29 Subject: modem1 Alphabet: ISO8859-15 This is the Text that I have sent with my mobile phone to the computer. |
From | Senders phone number. |
From_SMSC | The SMS service centre, that sent you this message. |
Subject | The name of the modem that received this message. |
Sent | Time when the message was sent. |
Received | Time when the message was received by the program. |
Alphabet | Tells the character set of the message text. |
The filenames of received SMS look like modem1.xyzxyz. They begin with the name of the modem that received the message, followed by a dot, followed by six random characters.
Status Reports
You can request and receive status reports, if the SMSC and your modem support this feature. Example:
Some header lines, as described above SMS STATUS REPORT Message_id: 117 Discharge_timestamp: 00-02-21 22:27:01 Status: 0,Ok,short message received by the SME |
Message_id | This is the ID number of the previously sent message, where this status report belongs to. The SMSC gives each sent message such a number. You can use eventhandler scripts, if you need to store the ID's of sent messages. |
Discharge_timestamp | This is the time, when the message was successfully delivered or when it was discarded by the SMSC. |
Status | The status of the message. Please take a look into the source code src/getsms.c if you need a list of all possible status codes. |
More header lines
The program supports some more header lines, that can be used to override settings from the configuration file.
SMSC | Phone number of the SMSC |
Provider Queue |
Name of the provider, can be used to override the normal sorting algorithm configured by [provider] and [queues] in the config file. Both keywords do the same. |
Report | Boolean value. Controls if a status report is requested for this message. |
Autosplit | Boolean value. Controls if the program shall split the message automatically in case it is larger than 160 characters. |
