Streams Release Notes 2.24
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.

●
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.

utility:
+ixon
●
Added support for dual micro channels on NCR3550
●
Added support for MEGAPORT/2 12 FM
