Description
011 = +5 Edge rate (slowest).
010 = +4 Edge rate.
001 = +3 Edge rate.
000 = +2 Edge rate.
111 = +1 Edge rate.
110 = Default edge rate.
101 = –1 Edge rate.
100 = –2 Edge rate (fastest).
The following are approximate lengths:
000 = < 10 m.
001 = 10—20 m.
010 = 20—40 m.
011 = 40—80 m.
100 = 80—100 m.
101 = 100—140 m.
110 = 140—180 m.
111 = >180 m.
This is a sticky bit.
1 = Enabled.
