Look at http://www.hendrik-sattler.de/scmxx/
It uses the same protocol as most Siemens phones.
You should be able to retrieve the information from the available source code.

I think you can use DTE-DCE interface defined in GSM specification. I have used my Nokia 8310 and Ericsson T39 do some similar things. Although I don't have a SL45 in hand now, I think it should support the standard.

To setup the connection between PC and SL45. You need a PC with Ir Port.
- Place the SL45 near the PC.
- Use some tools which can set some data to COM port.
- Connect to the Ir COM and open the port.
- Try to send an AT command to SL45. That's mean that your siemen phone should support the standard. Then you send SMS with ur PC thru your mobile.

Hi svindler,

I have a SL45 and I'm currently developing an app to send and receive SMS messages. The SL45 has a bilt-in GSM modem and understands standard and extended AT commands. Just put it in your docking station and open a terminal program (windows hyperterm, for example). Set the connection parameters (COM port, 19200bps, 8-N-1, no handshaking) and connect to it. Then, type AT and ENTER. SL45 should answer OK.

Now you can start sending GSM commands... and the next problem will be the PDU (Progrm Data Unit) format. SL45 doesn't accept clear text messages, that makes it a little more complicated. If you want to learn more, here're some addresses.

GSM AT commands:

Hope that helps
