I see tons of connection errors and filtering these out I see some packets that might have meaning.
imitating these send-out packets from Linux I don't get any response from the WMR-89.
My (may be false) judgement on this is, that there is going on some side band communication
with RS232 status lines, which could explain the errors. La Crosse is known to do these kind of things,
may be Oregon Scientific also decided to go that way for any reason. But as said, this is
momentarily just an impression I have and I would be interested to get feedback from
others in the forum who also tried to identify a polling schema in the WMR-89 communication.
Am I really the only one looking at this?
