</div>gsmd is not longer used by Openmoko. You best bet would be ogsmd by <a href="http://freesmartphone.org" target="_blank">freesmartphone.org</a><br>

</div>Not possible. Linux kernel and GSM stack are running on two separated CPUs.<br>
Arm based samsung SoC for the linux kernel and TI Calypso for the GSM side. The<br>
only communication between these two are a serial line where AT commands are<br>
spoken.<br>

</div>AFAIK SAP is only possible if the bluetooth stack runs on the same CPU as the<br>
GSM stack and has direct access to the SIM card. That is not the case on the Neo<br>
1973 and the Neo Freerunner.<br>
<br>
As long as you don't know a way to export the SIM informations you need for your<br>
SAP server over plain AT commands I see no way to make this possible.<br>
