in all communica

using the supervisor message aSU, S=N.
Examples:

(reques
t of wind data while all the wind parameters were disabled from the wind message)
1XU!0TX,Sync/address error<cr><lf>
(wrong device address. Ask the correct address with ? or ?! command.)
0XP!0TX,Unknown cmd error<cr><lf>
0xUabc!0TX,Use chksum CCb<cr><lf>
