_______________ Bugs Fixed in ComOS 3.8.2

The following bugs have been fixed in ComOS 3.8.2.

	Improved Modem Support

* A timing problem with V.32 modems is fixed.
* A rate renegotiation and retrain issue with U.S. Robotics (USR)
  V.90 modems is fixed.
* A disconnect problem that occurs when V.90 falls back to V.34 is
  fixed.
* A timing problem with LT WinModems is fixed.
* A USR V.90 "No Connect" problem is fixed.
* A latency problem is fixed, improving ping times and reducing game latency.
* A V.34 renegotiation issue is fixed (including the upstream part of
  V.90 and K56flex).
* An A-law rate renegotiation problem is fixed.
* The LAPM retransmitter in V.90 is improved.


	X.75 Large Frames

X.75 on the PortMaster 3 now supports 2048 octet packets.  In 
previous releases, the PortMaster 3 crashed upon receiving a large
X.75 information frame (I-frame).


	Fractional E1 Channel Numbering

Fractional E1 channel numbering is now correct.  In previous releases,
the channel numbering was off by one.  For example, you had to specify
channel 2 for channel 1 when configuring a fractional E1 line.


	Net5 Dial-Out When Inactive

When using the Net5 ISDN switch type, the PortMaster 3 now attempts to
activate Layer 2 if it is inactive during a dial-out attempt.  In
previous releases, if a Net5 ISDN switch initiated a Layer 2 inactive
state, the PortMaster 3 did not activate Layer 2 again before attempting
an outbound call, and the call failed.


	MFR2 Tones Conform to ITU Standards

Multifrequency R2 signaling (MFR2) tone timing used in Interregister
signalling phase or R2 is now in conformance with the ITU standards for
MFR2 tones.  In previous releases, MFR2 tones were sent for a fixed
length of time.


	MFR2 Receive Threshold

New receive thresholds now determine the sensitivity of the MFR2
tone detector.


	Microsoft Windows 95 and 98 Analog Multilink PPP Improved

Throughput on an analog Multilink PPP (MP) connection from a Microsoft
Windows 95 or Windows 98 machine has been improved.  In previous
releases, throughput was very poor when using analog MP from a
Microsoft Windows 95 or Windows 98 machine.


	PMVision Password Backup

PMVision 1.3 can back up the RADIUS and ChoiceNet(R) secrets,
and user table passwords, from ComOS 3.8.2.  The administrative
password is not backed up.


	Static Routes

Static routes are no longer overridden by OSPF routes.


	Large Syslog Messages Handled Correctly

Memory is no longer overwritten by large syslog messages.


	System Block Leak Fixed

The PortMaster 3 now discards malformed PPP packets containing only
one byte of PPP data.  In previous releases, receiving a malformed PPP
packet that contained only one byte after escape characters were
removed caused the PortMaster 3 to lose a system block.


	Reset after Lastcall

In previous releases, a modem that entered the ADMIN state as a result of
the use of the lastcall command required a 'set m0 off' and a 'set m0 on'
to return it to the READY state.  In this release only a 'set m0 on' is
required.


_______________ New Features in ComOS 3.8.2

No new commands or features have been added in ComOS 3.8.2.



_______________ Upgrade Instructions

You can upgrade your PortMaster 3 using PMVision 1.2, pmupgrade 4.0 from
PMTools, or using the older programs pminstall 3.5.3, PMconsole 3.5.3, or
PMconsole for Windows 3.5.1.4, or later releases.  You can also upgrade
using TFTP with the "tftp get comos" command from the PortMaster command
line interface.

*** CAUTION!  If the upgrade fails, do NOT reboot!  Contact Lucent  ***
*** Remote Access Technical Support without rebooting.  	    ***

The upgrade process on the PortMaster 3 erases the configuration area
from nonvolatile memory and saves the current configuration into
nonvolatile memory.   Never interrupt the upgrade process, or loss of
configuration information can result.  This upgrade does not otherwise
affect your stored configuration in the PortMaster 3.

The installation software can be retrieved by FTP from
ftp://ftp.livingston.com/pub/le/software/ and the upgrade image
can be found at ftp://ftp.livingston.com/pub/le/upgrades:
