          The following  changes/additions  were  made  in  internal  build
          0.113.

               The initialization  procedure for enabling the  FIFOs of the
               16550  was changed  as per  directions from  StarTech.   The
               StarTech 16550 is used in many Practical Peripherals modems.
               This  change may  correct overrun  and hanging  problems for
               other  users.     User  reports  indicate   that  the  FIFOs
               initialization problem may go  beyond the StarTech 16550 and
               thus, solve problems for users of other 16550s.
