Subject: [PATCH] Fixed initialization of TS_CONNECTED bit in t_state.  It
 wasn't set in open() when CLOCAL is set unless carrier is present.

Fixed initialization of line discipline.  It lived across opens.
Lines that started with the wrong discipline probably didn't work
at all, because TS_ISOPEN is only set by TTYDISC.
