Read returns zero.
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.
Linefeed.
Writing to this register sets the linefeed state.
