          1. Changes

          This release is a feature upgrade of the  UnixWare  RealPort
          Software.

          The UnixWare driver is now a loadable module.  There  is  no
          need to reboot your system after the driver package has been
          installed.  This also allows the capability of only updating
          the  software  drivers  without  reconfiguring  the RealPort
          devices.

          Also, it is now possible to use the UnixWare Serial  Manager
          (Unix  Ware  7.1.0  and  later)  to set up port monitors for
          RealPort.

          The OSR5 driver  now  supports  the  higher  baud  rates  in
          OpenServer.  It is also possible to set the higher baud rate
          without using the fastbaud option on  ditty.   The  fastbaud
          flag is still available for earlier versions of SCO.

          Man pages have  been  added  for  the  RealPort  daemon  and
          configuration program (ncxd.1 and ncxaconfig.1).

          The ditty printer option was modified to allow  the  printer
          connection  to  close  without  losing  the current terminal
          settings for that port.


          2. Bug Fixes

          A problem where a nohupped process could  prevent  the  ncxd
          daemon  from  reconnecting  properly  to  the PortServer was
          fixed.

          Fixed a  problem  where  the  RealPort  software  failed  to
          determine  the  correct  number of ports whenever EM modules
          were added or deleted.

          A timing problem in the driver  could  result  in  a  kernel
          panic on a multi-processor machine.  This has been fixed.


          3. Known Limitations

          Under UnixWare, the open count for the RealPort devices  are
          sometimes  reported incorrectly by the OS.  This may prevent
          the  driver  from  being  unloaded.   A  system  reboot   is
          necessary to clear this up.

          If the network  connection  is  lost  between  the  RealPort
          driver  and  the  PortServer,  it  may  take several minutes
          before  communications  can  be  re-established   with   the
          PortServer.
