  Modified files:
    sys/i386/isa         cy.c 
  Log:
  Fixed sloppy clearing of TS_BUSY.  Don't clear it until the transmitter
  is completely empty.  There is an interrupt for output completion.  It
  is painful to use, but polling method used in the corresponding fix in
  sio.c (rev.1.152) can't be used because there is no status bit for
  transmitter-empty.  Now ttywait() works right.
