Hi. I am using a HP IPaQ Data Messenger, and am noticing that it will report empty NMEA sentences. Why could this be happening? (see bold section in the dump below)

If your immediate thought is, "contact the device manfacturer", please could you suggest someone to contact at HP, since I don't want to be channelled through the numptys who read scripts of how to change printer cartridges ;)
