Solution Specifics

1. General Description

These release notes acquaint you with the contents of UnixWare 
PTF130 - Fix for UnixWare/NetWare connections lost problem. 
This package has libnwapi.so, nwncp/Driver.o, nucamd and nucmessaged 
in pkgadd format.

2. Software Notes and Recommendations

This ptf is meant for UnixWare version 1.1 or 1.1.1 or 1.2. It modifies files
found in ptf142, update1.1.1 and update 1.1.2

There were four fixes done to correct these problems:
     
i. nucmessaged was getting killed when it recieves an error. Now it is
corrected to continue its operation by logging a message. ncp driver used to
retun GENERAL_FAILURE error when a zero length message is received. 
nucmessaged was breaking out of the loop because of this error. Now the zero
length messages are ignored by ncp driver.

ii. nwapi library got changed to take care of connection status, to pass the
return value to reflect the all possible connection status values.

iii. ncp driver got changed to take care of packet size.

This driver needs UnixWare 1.1 to be installed on the system.  It is part of
UnixWare 1.1.2

iv. nucamd is modified to cleanup the NWMP tasks properly, once the task
serves its purpose.

3. Hardware Notes and Recommendations

No specific Hardware.

4. Installation Instructions

     # pkgadd -d diskette1 should install this driver.
