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).
