When I tested this under FSO I checked that it was persistent over multiple calls. It remained until I explicitly disabled it with AT%N0001 mid call several calls later to check the effect back to back. I may retest this in case I missed something. Are there any resets of any sort in there that could undo the setting? Unless there's a delay involved I can't see any harm in sending AT%N0187 at the start of every call. _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
