  Modified files:
    usr.sbin/ppp         modem.c physical.c physical.h 
  Log:
  Only call isatty() when we open our descriptor, and remember
  the answer.
  
  If we later get a descriptor exception from select(), we know
  that it's a tty (isatty() returns 0 after the exception on a
  tty) and remember to call modem_LogicalClose().
  
  The upshot of it all is that descriptor exceptions dont leave
  the tty locked any more.
