Novell MHS Patch - M15CN4

This patch program repairs the following problems with MHS
1.5CN Rev.B:

1) When MHS messages are upgraded from SMF-64 to SMF-70, MHS might reject
the message indicating "Bad Expiry Date Header".  This problem occurred
every 256 days; the last known date on which it occurred was January 7,
1992.

2) MHS would fail when it connected to the Compuserve Mail Hub from outside
the United States, if the connection was made through a data network that
uses 7-bit data.

3) Although it was using the "DISABLED" modem driver, MHS would still
require the selected COM port to be present, and would alter the settings
of that COM port. MHS no longer accesses the COM port when using the
"DISABLED" modem driver.

4) Under some circumstances, the MHS workstation would hang if activity
occurred on the COM PORT while a gateway was running. This has been
corrected.

5) Sometimes during message queue transfers, the warning message "Dangerous
stuff" would appear. The condition causing this problem has been
eliminated.

6) Disk write errors that occur during INET message deliveries are no
longer considered fatal errors. MHS will now count that as 1 failed
connection attempt and continue processing.

7) Some common INET delivery errors used to cause immediate deactivation of
the INET host. All errors now accumulate as single failed connections and
the host is deactivated when the system retry limit is reached.

8) On faster machines, the Connectivity Manager would sometimes terminate
with a fatal runtime (division by zero) error.

Note:  The first seven (7) fixes were included in previous patches. This
patch identifies which of these fixes have already been applied and will
only apply those that have not.
