I was installing FSO to try those commands too. I just tried AT%N0187 and it works. If you push the mic gain right up it will eventually start to break through, but this is _much_ better than before. It's really easy to run on FSO as gsm0710muxd and mickeyterm are already running. Just start a terminal, run mickeyterm and issue the AT command, then exit with Ctrl-D. All subsequent calls will be affected. You can even turn it off again mid call using AT%N0001 if you want to compare back to back. I haven't tried fine tuning with any of the other values yet. _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
