Thank you very much - I'll have it soon.

Only if they also export data on multiple channels and the channel on which
they provide NMEA output is the one with the greatest number.

I just added "&& iremotechannel == 255" to the logic that assigns the channel
numberso that it always selects the first available rfcomm channel.

One glich remains which I'm going to fix now: Garmin GLO reports subsecond
times which Loadstone does not understand, and keeps thinking that the time is
always 00:00:00. Garmin's time string is something like HHMMSS.SUB where SUB
is the subseconds part. When this is done, the receiver is fully functional.

I have one final question: Is the original Loadstone's documentation still
available somewhere. I would like to have it, even though I believe that I can
use the software pretty well. There are some features that I don't use and if
I once need them, the docs would be faster to read than Symbian C++.

I'm very grateful for all the help I received. I wish happy winter to
everybody (and some other season for all those who live onn a different climate
zone than I).
