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

	   MPI V3.2.4:

	  1. Enhancements

	  None

	  2. Bug Fixes

	  Updated firmware to address performance issues on high speed
	  lines.

	  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.

	  The  T1  modem bank is only supported	under SCO OpenServer 5
	  releases.

	  When the machine is configured for T1	 modem	banks,	system



				      -	1 -






	  defaults  in	the /etc/snmpd.comm file only allows the local
	  machine to do	writes.	 If you	want  Quick  Manager  (or  any
	  other	machine) to be able to write to	the local machine, you
	  must add an entry in	the  /etc/snmpd.comm  file  for	 write
	  access,  and	use the	new community name when	adding the new
	  computer in Quick Manager.  See the man page	on  snmpd.comm
	  for more details.

	  The  T1  modem  bank line card can be	configured by entering
	  the command "t1util -d <device_name>"	where  device_name  is
	  the  name of the utility channel "/dev/t1mbx31" and x	is the
	  module ID used when configuring the modem bank through  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.

	  Due to the nature of modems and printers, the	Shutsave  fea-
	  ture does not	provide	seamless execution for processes using
	  these	devices	in the event of	a power	failure.

	  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.

	  This version does not	support	SCO XENIX.

	  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.

	  DOS Merge com	port  attachment  is  not  supported  for  SCO
	  3.2v2.

	  4. Manual Errata

	  None
