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
