Learning something new every day. Until know I thought they had a clear split between "Qualcomm" and "Sierra" protocols, but these devices obviously do a mix. Is the NMEA port Sierra style (enabled using the SetNmea control message) or Qualcomm style (enabled by writing "$GPS_START" to the port)? Bj=C3=B8rn --===============4740867754066660739==--
