DOCUMENT ID:        TID300212
DOCUMENT REVISION:  A
DATE:               11MAY95
ALERT STATUS:       Yellow
INFORMATION TYPE:   Symptom Solution
README FOR:         ptf265

PRODUCT and VERSION:
UnixWare 1.1

ABSTRACT:

Installs a new clist driver with support for all tcgetattr/tcsetattr options.
The clist driver consists of a set of generic tty support routines that are
used by non-Streams tty drivers.


SYMPTOM

Prior to the installation of Update 1.1.3 (or PTF144), any call to 
tcgetattr or tcsetattr for a non-Streams tty driver would return an 
EINVAL error. After the installation of Update 1.1.3 (or PTF144), 
using stty to change the driver's options results in an 
"ERROR: Invalid argument" message (EINVAL error).

SOLUTION

Apply the ptf265 file.


Installation Instructions:  

DATATYPE: datastream

1.  Download the ptf265.Z and ptf265.txt files to the /tmp directory  
    on your machine.

2.  Read the release notes contained in this file and follow the
    instuctions to add the packages to your system.

3.  Now become root, uncompress the file and add the package to your 
    system using the following commands:

        $ su
        # uncompress /tmp/ptf265.Z
        # pkgadd -d /tmp/ptf265

PTF265 - Full tcgetattr/tcsetattr Support For non-Streams tty Drivers

Product And Version
--------------------------

UnixWare 1.1.1, UnixWare 1.1.2., UnixWare 1.1.3, UnixWare 1.1.4

General Description.
-------------------

The updated clist driver released with Update 1.1.3 implemented support
for the most often used options of tcgetattr/tcsetattr (or, more
precisely, the associated ioctl() requests).  This partial support
resulted in stty then using additional (and not yet supported) options
when attemtpting change driver options.

This PTF installs a new clist driver which supports the full range of
ioctl() requests issued by tcgetattr/tcsetattr.

New Features.
------------

None

Software Notes and Recommendations.
----------------------------------

This PTF should be installed on all UnixWare 1.1.1 through UnixWare
1.1.4 systems which have the Enhanced Application Compatibiliy (acp)
package installed.  If, after installing this PTF, Update 1.1.3 and/or
Update 1.1.4 is subsequently installed, it will then be necessary to
reinstall this PTF.

Testing of the modified software contained in this package has been
conducted only to the extent necessary to confirm that it resolves the
problem(s) stated above ("Symptom").  Such testing consists of
recreating the problem conditions and verifying that the problem no 
longer occurs.  No other testing of this software has been done.

Hardware Notes and Recommendations.
----------------------------------

This PTF is targeted for the i386, i486 and Pentium CPU's.
