                                V1.1.1

                              HP-UX 10.20 & 11.x

              Software Package P/N 40002143_C  V1.1.1

                                O5/09/02

       INTRODUCTION:

            This Digi software package includes device drivers for
            PCI adapters in the AccelePort Xp and AccelePort RAS product
            families.   It supports up to thirty-two adapters and
            includes all necessary driver binaries, firmware images,
            configuration scripts, etc.  It may be installed with the
            standard HP-UX software installation utility ``swinstall''.

       SUPPORTED PRODUCTS:

            AccelePort 2p PCI, AccelePort 4p  PCI,  AccelePort  8p  PCI,
            AccelePort 16p PCI

            AccelePort RAS 4, AccelePort RAS 8

       ENHANCEMENTS:

            Adds support for HP-UX 11i.

            Adds support for the TIOCSETP and TIOCGETP ioctls

            Updates AccelePort RAS firmware to M

       BUG FIXES:

            A problem  was  fixed  that  occurred  when  other  DIGI  PCI
            adapters  (not  associated  with this driver) were loaded by
            the operating system after this driver was loaded.  If a PCI
            version  of  the DIGI Xr, Xr/920, Xem, EPC/X, or C/X adapter
            were in the system, there were  potential  serious  problems
            depending  on  what order the operating system installed the
            adapters.

       KNOWN LIMITATIONS:

            This package does not support machines running on  the  IA64
            architecture.

            The cu application does not behave correctly when "Any"  is
	    specified  for the device line in the uucp/Devices file.  To
            avoid this problem a specific baud rate  must  be  specified
            instead.   The standard HPUX serial port does not have these 
            problems because it does not  lower modem  controls  signals
            when a baud rate of 0 is specified.  This behavior is 
            contrary to  what  HPUX  specifies  in  its documentation 
            and   what   is   specified   by  the  POSIX specification.

            This package must be installed after  any  version
            of Digi's EPCA driver or Digi's DRP (RealPort) driver.

            The following patches may be required if you have  a  multi-
            processing environment.  Contact HP technical support if you
            need help determining whether these patches are necessary on
            your machine:

                 PHNE_20008

                 PHKL_16209

            Some of the tools in the package (for instance,  dm_gui  and
            dm_admin) support a maximum of four adapters.

       HISTORY:

            1.1.0

                 Support has been added for HP-UX 11i.

                 A problem has been fixed in the firmware where  a  RING
                 condition was not showing up.

                 The pause in the dial string has  been  set  to  at
                 least 3 seconds.

                 The tools which allow for the  selection  of  arbitrary
                 custom  baud  rates  did  not  return  the  actual rate
                 selected by the firmware  causing  some  confusion  at
                 high  baud  rates  (where  not  every  integer  rate is
                 strictly possible.)

                 The driver was sometimes reporting an incorrect version
                 of the state of hardware flow control.

                 A bug with dm_gui has been fixed  that  did  not  allow
                 parts  of this application to be accessed under certain
                 environments.

            1.0.0:

                      Initial release.
