We'll get false negatives on this (I can send 999 waypoints 10 times and not
trigger it) but I was thinking that we can indeed catch the case that we
*know* will fail and head that off.  I actually had something very much like
this in a debugger last night.  I did the capabilities groping during
conversation startup instead of waypoint transfer so I could use it for
tracks and routes, too.

We also can't catch
   gpsbabel -i gpx -f 900.gpx -o delbin -F usb: -i gpx -f 900more.gpx -o
delbin -F usb:
with this approach, either.  I kept dwelling on 'perfect' and maybe 'good
enough' on this is exactly that.

I've applied this.    Thanx.

I deduce you're a GSAK user watching that conversation...
