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 :-) matthias -- Matthias Apitz e <guru@unixarea.de> - w http://www.unixarea.de/ UNIX since V7 on PDP-11, UNIX on mainframe since ESER 1055 (IBM /370) UNIX on x86 since SVR4.2 UnixWare 2.1.2, FreeBSD since 2.2.5
