ComOS 3.7.2 Release Note
Introduction
The new Livingston Enterprises ComOS(TM) 3.7.2 software
release is now available for the PortMaster(R) 3 Integrated Access
Server. This release note applies only to the PortMaster 3. This
release is provided at no charge to all Livingston customers.
This release note documents commands and features added between ComOS
release 3.7.1 and 3.7.2 on the PortMaster 3.
Note - You must use PMconsole(TM) 3.5.3 when upgrading to ComOS 3.7.2;
see "Upgrade Instructions" below. If you are running Windows 95 or
Windows NT 4.0 you must use PMconsole for Windows 3.5.1.4. ComOS 3.7.2
uses roughly the same amount of memory as ComOS 3.7. Read "Upgrade
Instructions" thoroughly before upgrading.

Upgrade Instructions
New Features in ComOS 3.7.2
ComOS 3.7.2 now supports semi-permanent connections (SPC) on switch
type ts014 in Australia. To set up a SPC with switch-type ts014, set
the port type to network hardwired and set the directory number for the
port to the SPC ID, then reset the port.
Bugs Fixed in ComOS 3.7.2
The "show modem" command no longer displays non-existent modems in
the ADMIN state when using 8-modem cards. The non-existent modems may
show up in the first two minutes after reboot, but will not be displayed
in normal operation after that.
In ComOS 3.7.1 some modems on the True Digital 56K Card would sometimes
enter the ADMIN state incorrectly. In some cases the "set M0 on"
command would return the modem to the READY state, but in other cases
the PortMaster required a reboot to return the modem to the READY state.
In ComOS 3.7.2 the three reasons a modem might enter this error state
have all been fixed.
A bug in ComOS 3.7.1 causing modem disconnects following retraining
(rate renegotiation) is fixed in ComOS 3.7.2.
The modems on the True Digital 56K Card have been improved to
provide higher connect rates and more stable operation.
ComOS 3.7.2 fixes a bug where Multichassis PPP (MCPPP) on the two E1
model of the PortMaster 3 would sometimes crash the PortMaster.
RADIUS accounting records are now properly generated on Multi-Chassis
PPP (MCPPP) sessions.
Multilink PPP (MP) sessions now successfully establish multiple links
arriving simultaneously in all cases.
Upgrade Instructions
WARNING! YOU MUST USE PMINSTALL VERSION 3.5.3 OR LATER TO PERFORM THIS
UPGRADE! If you are upgrading using PMconsole for Windows, you must use
PMconsole for Windows version 3.5.1.4 or later.
If you are upgrading from ComOS 2.3 or 2.4 to ComOS 3.7.2, you must
first upgrade to ComOS 3.0.4, reboot, and then upgrade to ComOS 3.7.2.
*** NOTE! If the upgrade fails, do NOT reboot! Contact Livingston ***
*** Technical Support without rebooting. ***
The upgrade process on the PortMaster 3 erases the configuration
area from nonvolatile memory and saves the current configuration into
the nonvolatile memory. Never interrupt the upgrade process, or loss
of configuration information can result.
The upgrade does not otherwise affect your stored configuration in the
PortMaster. If you want to back up your PortMaster configuration before
upgrading, choose the Backup PortMaster button in PMconsole for
Windows, or run pmreadconf on UNIX. The pmreadconf utility takes three
arguments: the hostname or IP address of the PortMaster, the
administrative password for the PortMaster, and the filename to place the
configuration in. If you ever need to reload the configuration, move
the backup file into the /usr/portmaster/data directory and run
pminstall to reload it. Here is an example:
cd /usr/portmaster
pmreadconf Pmname Pmpassword data/Pmname.conf
chmod 600 data/Pmname.conf
The installation software can be retrieved by FTP from
ftp://ftp.livingston.com/pub/le/software/System/Tarfile.tar.Z,
replacing System and Tarfile.tar.Z with the names of the files. You
can retrieve the upgrade image at the same time. The following example
shows an administrator retrieving the SunOS pminstall and PortMaster 3
upgrade image:
umask 22
mkdir /usr/portmaster
cd /usr/portmaster
ftp ftp.livingston.com
(Enter anonymous)
(Enter your email address; it will not echo.)
binary
cd /pub/le/software/sun4
get pm_3.5.3_sun4.tar.Z pm.tar.Z
cd /pub/le/upgrades
get pm3_3.7.2
quit
uncompress pm.tar.Z
tar xvf pm.tar
rm pm.tar
mv pm3_3.7.2 data
pminstall
PMconsole 3.5.1.4 for Windows 95 and Windows NT 4.0 is available on
ftp://ftp.livingston.com/pub/le/software/pc/pmw3514.exe in a
self-extracting file. Transfer that file via FTP, run the file to
install PMconsole for Windows, move the upgrade file into the data
directory, run PMconsole for Windows, and click on the Upgrade icon.
