ENGINEERING RELEASE NOTES
-------------------------

Title
-----
	PTF287 - Allow More Simultaneous telnet Sessions

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

	UnixWare 1.1.2, UnixWare 1.1.3, and UnixWare 1.1.4

Abstract
--------

	This PTF contains updates to the UnixWare telnet command
	to allow more simultaneous sessions.

Symptoms
--------

	A single process that manages the input and output for
	multiple telnet sessions would fail to register input
	after four or five sessions were started.  All telnet
	sessions would get the "Connected to ..." message, but
	the after the fourth or fifth session, no login prompt
	is printed.  An 'in.ftpd' process is spawned on the
	telnet host, however.


SOLUTION SPECIFICS
------------------

General Description
-------------------

	Increase the number of file descriptors scanned by the
	'select()' system call in the telnet command.  The limit
	had been 16 previously, it is now set to 1024.


New Features
------------

	None
