Linefeed Shadow.
This register reflects the actual real time linefeed state. Automatic operations may cause
actual linefeed state to deviate from the state defined by linefeed register (e.g., when
linefeed equals Ringing state, LFS will equal on-hook transmission state during ringing
silent period and Ringing state during ring burst).
000 = Open
001 = Forward active
010 = Forward on-hook transmission
011 = TIP open
100 = Ringing
101 = Reverse active
110 = Reverse on-hook transmission
111 = RING open
Read returns zero.
