Hi,

At the end I decided to understand the source code. Btw: the device port
/dev/cuaU0.n is hardcoded set to .2, while mine is .3 for the E1750;

the -51 dBm value is just nothing more than the best possible RSSI value
31; 

the #-line (which is in real a fine line of some ncurses(3) symbol, don't
know why cut&paste changed this) is a scaled representation of the RSSI
values of the last 80x two seconds;

the byte value in line 13 of 400kB is always calculated as the max or RX
or TX values of the last 80x two seconds history;

and finally 'v' and '^' are used to represent the current RX or TX value
in scale with this maximum;

I will now watch this movie for a while and see if I can draw some clue
from that graphic :-)
