Thats a nice function :o)

You use the same configuration as you would via a terminalprogram.
If the digipeater callsign are LD5BE you can connect to this changing
your UNPROTO to LD5BE
Send a "empty" packet and the TNC responds with a string.
Put this string into a calculator and send the result back.
If password is ok then you can change everything but the callsign.
If i want to check the UITrace i just send "T?"
To change the parameter "T WIDE"
So it's a different approach than the T2 regarding the change of
parameters via RF.
Upgrading firmware over the air sounds spooky ;o) is there a fallback if
