	   This	DigiWare software package includes device drivers for
	  Digi Xe, Digi	Xr, EPC/X, C/X and Xem product families.  This
	  package also contains	Digi's MenuPort	Interface (MPI),  Port
	  Configuration	 Utility (PCU),	and Digi Port Authority	(DPA).

	   MPI V4.2.0:

	  1. Enhancements

	  Removed AccelePort RAS support.

	  Added	changes	so the package	is  compatible	with  the  new
	  software  package  dgap that will now	support	all AccelePort
	  RAS, DataFire	RAS and	AccelePort Xp adapters.

	  2. Bug Fixes

	  Corrected a lock timeout panic condition that	occurs on  SMP
	  systems.

	  Fixed	 ditty so that it can be used by a non-root user with-
	  out getting errors printed out on the	console.

	  3. Known Limitations

	  If multiple Xr(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  you get errors on	boot that say "Another Process Waiting
	  on Open", you	can put	the command "sleep 10"	as  the	 first
	  line in "/etc/rc.d/8/pcuepca"	which will delay the execution
	  of the ditty commands	 until	the  download  process	has  a
	  chance to complete.

	  At  this point, the driver supports PCI initialization using
	  the built in PCI BIOS	routines.  If the hardware or software
	  does	not allow use of the PCI BIOS routines,	the board ini-
	  tialization will fail.

	  The device driver update function from MPI v2.0.1 or earlier
	  may not work properly	with later versions of MPI.

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

	  Canonical input ttyhog processing works  slightly  different
	  than	might be expected. If the UNIX input highwater mark is
	  reached without the eol character  being  received,  echoing
	  stops	 until the board's input buffer	overflows or an	inter-
	  rupt character or break is received.

	  Scancode terminals, under VP/ix, must	be  configured	for  8
	  databits,  1 stop bit, and no	parity as scancodes are	8 bits
	  wide.

	  4. Manual Errata

	  None

	  5. History

	  MPI 4.0.0

	    - Added AccelePort RAS support.
