          1. Introduction

             This Digi software package includes device drivers for
             Digi EPC/X PCI, C/X PCI, Xem PCI, Xr920 PCI and Xr PCI
             product families.

             This software package has been tested under SCO OpenServer 6,
             and SCO OpenServer 6 with Maintenance Pack 1.

             This package also contains Digi's MenuPort Interface (MPI),
             Port Configuration Utility (PCU) and Digi Port Authority (DPA).

          5. Known Limitations

             During package removal on OpenServer 6 Maintenance Pack 1,
             you may receive a warning similar to the following:
                 UX:pkgremove: WARNING: e-mail notification may have failed
             The warning message is harmless and can be ignored.

             If multiple Xr(PCI) or Xr920(PCI) cards are being configured,
             and the cards support different numbers of ports, make sure
             the card placement on the PCI bus match the order in which
             they are configured in MPI.

             If Digi loadable drivers are removed but not reinstalled
             the user is advised to relink the kernel prior to rebooting
             the UNIX  system.

             The time to perform various stages	in the MPI install and
             change process can vary widely depending on when the idbuild
             for a driver is done.  Since the idbuild for a driver
             cannot be done while the driver is loaded, MPI will do the
             build at one of three different times:

             - Driver not loaded - build is done during	configuration

             - Driver was changed while	it was loaded and is now being
               reloaded	- build	is done	during load

             - Driver was changed while it was loaded and the system
               is now being rebooted - the build is done during the
	       load that occurs	after the boot

             MPI must be run after pkgadd to install new products.

             Before the MPI package can be removed from the system,
             the remove	installed products option must be invoked
             through MPI to remove all configured Digi drivers.

             Executing pkginfo -l on the MPI package will display a
             message of partially installed pathnames.
             This message can be ignored.

             The ditty printer option does not guarantee complete
             writes of data to slow printer devices unless the tcdrain
             mechanism is used.

             For maximum performance of throughput, all of the
             concentrators should be evenly divided between the 2 lines.
