Streams Release Notes 2.24
Unix System V, Release 4 STREAMS
Release Notes Version 2.24
This document is for use with UNIX System V Release 4.X and the Equinox MEGA-
PORT/2 Streams driver (Version 2.24 or greater). These release notes contain a
description of the driver release and other information not included in the printed
manual.
These release notes are intended as a supplement to the following manuals:
SVR4 Streams Device Driver Software Reference Manual, Equinox part number
560071/Rev A;
MEGAPORT; MEGAPORT/2; MEGAPORT/RS Hardware Reference Manual,
Equinox part number 560047/Rev A;
MEGAPLEX/; MEGAPLEX/2; MEGAPLEX/RS Hardware Reference Manual,
Equinox part number 560050,/Rev A.
If you do not have the appropriate installation manual, contact your distributor or
other point of purchase to obtain one.
NOTE: If you are using UNIX 3.2 you should use the standard
Equinox UNIX driver. If you are using SCO XENIX, you should
use the Equinox XENIX driver diskette.
Upgrading From Previous Releases of Device Driver
MEGAPORT/2 & MEGAPLEX/2 Streams Device Driver Version 2.X represents a
major change in the format of the device driver distribution floppy. The SVR4-style
pkgadd format is now utilized. Users upgrading from previous versions of the device
driver must take some additional steps to insure proper installation.
Device drivers formatted to work with the SVR4 pkgadd utility require previously
installed versions to be manually removed before installing this release. If you are
upgrading the Equinox MEGAPORT/2 or MEGAPLEX/2 Streams device driver,
check the version of the currently installed device driver. Follow the appropriate
instructions described below. If you are not sure of the version number installed on
your system, run both sets of procedures. Only one driver will be removed.
Device Driver Version 1.2X and Lower
If you are currently using version 1.2X or lower of the Equinox Streams device
driver, or if you are not sure which version you are using, execute the following
command:
# removepkg <CR>
removepkg produces a list of packages which were installed using the installpkg
command. If an Equinox device driver appears in the list, select the number corre-
sponding to the driver and proceed with driver removal. This procedure removes the
device driver version 1.2x and lower.
Do not rebuild the kernel at this time. The rebuild can be done after the new driver
is installed.

MEGAPORT/2 & MEGAPLEX/2 4
Streams Release Notes 2.24
Device Driver Version 2.00 and Higher
If you currently use version 2.00 or higher of the Equinox Streams device driver, run
the pkgrm command. A prompt displays if version 2.00 or higher of the device
driver was installed. Enter Yfollowed by a carriage return to remove the device
driver. The pkgrm utility removes packages that were installed with the pkgadd
utility.
Do not rebuild the kernel at this time. The rebuild can be done after the new driver
is installed.
# pkgrm eqx
The following package is currently installed:
eqx Equinox Megaport/2 Megaplex/2 STREAMS Device Driver (Micro Channel) (i386) 2.xx
Do you want to remove this package [y,n,?,q]
Once you have successfully completed at least one of the removal procedures dis-
cussed above, you are ready to proceed with driver installation.
Installing Version 2.24 Device Driver
Follow these steps after you have removed any previous device driver release:
Step 1 Run the pkgadd command:
# pkgadd -d diskette1
Step 2 The pkgadd command confirms your actions with the following prompt:
Type [ go ] when ready or [q] to quit:
Step 3 Enter the word go followed by <CR> to continue:
go
Step 4 A prompt displays listing the available package. Enter 1followed by a
<CR> to select the device driver packages:
1 eqx Equinox Megaport/2 STREAMS Device Driver
Step 5 The installation should continue in a normal manner from this point. Refer
to the sample installation provided in the SVR4 Streams Device Driver Software
Reference Manual, Equinox part number 560071/Rev A to guide you though the rest
of the installation procedure. After the installation is completed, the following
prompt displays:
Type [ go ] when ready or [q] to quit:
Step 6 Type q followed by <CR> to exit the installation procedure.
Step 7 Reboot your system to begin using the new driver.

Streams Release Notes 2.24
Packages Not Listed With pkgadd
If no packages are listed after you execute the pkgadd command, you must manually
mount and unmount the package disk. This appears to be a problem with some
versions of SVR4 in the implementation of pkgadd. Follow these steps to manually
mount and unmount the package disk:
# mount -Fs5 /dev/dsk/f03ht /mnt <CR>
# pkgadd -d /dev/dsk/f03ht <CR>
Follow the installation procedure outline in Installing Version 2.02 Device Driver. To
complete the installation:
# umount /mnt
Note: The device name /dev/dsk/f03ht refers to a 3½ inch floppy drive
configured as drive 0. Substitute 1 for 0 if your 3½ floppy is configured as
the second drive. Substitute the 3 with the number 5 if you are using a 5¼
diskette (i.e. /dev/dsk/f05ht) when drive 0 is a 5¼ diskette.
Ignore -ixon: +ixon
Some applications (such as FoxBase+) disable XON/XOFF software flow control (i.e.
-ixon). Use megastty with the +ixon flag to ignore -ixon on a port.
Example: When logged into a MEGAPORT port, entering the following to cause
a driver to honor XON/XOFF flow control independent of whether the
port is set up for -ixon, enter:
megastty +ixon
To disable the operation of this feature from a MEGAPORT port, type:
megastty -ixon

Release Summary 2.24
Enhancements and Fixes
●Fixed a panic reported by an NCR customer: when a port reported both a break
and a parity error in the same megapoll pass, it was possible for the driver to
corrupt a pointer eventually leading to memory corruption and a system panic.
The following impact NCR multiprocessor systems only:
●Removed a warning message inserted in an earlier release to confirm a sus-
pected problem and validate the file. The message will no longer be seen.
●Fixed a possible infinite loop in the channel lock code.
Release History
Release 2.23
●Added fix for transparent print driver to fix random panics.
●Increased print speed of printer driver.
●Modified to allow non-blocked channel processing on LD boards.
●MP version modified to eliminate timing window in unlock routine.
●Added mode entries in the "/dev/term" directory to allow for faster processing
of login security searches.
Release 2.22
●Reconfigured the driver to use "timeout" instead of "poll entry point" which is
not supported under UNIXWARE 2.0.
●Made changes to the multi-processor code to eliminate deadlock situations.
●Added support for Solaris x86. (See Solaris x86 release notes pn560081).
●Added power recover processing for NCR systems.
●Added Megaport/2 XP support.
●Modified open routine to unconditionally raise outbound control signals, fixed a
bug introduced in release 2.10.
●Corrected a problem which occurred during driver installation of a MEGAPLEX.
The driver did not recover cleanly if a resource error (memory collision) was
detected. This problem could cause a system panic.
●Corrected a problem on "dual SCSI" adapter systems. Problem primarily
manifested during normal system activity and accessing a "SCSI" tape de-
vice.
●Restored generic (non NCR) Micro Channel Initialization that was removed in
release 2.10.
●Corrected initialization "board not found [ECH]" messages.
Release 2.10
●Added flag to megastty utility: +ixon
●Added support for dual micro channels on NCR3550
●Added support for MEGAPORT/2 12 FM
●Fixed problem with eqxlpsetup utility for transparent print. This sometimes
caused the system to panic.
