ECO KIT SUMMARY:

An ECO (patch) kit exists for YxDRIVER on OpenVMS VAX V5.0 through
V5.4-2. This kit contains the following fixes/problems:

YCDRIVER:

o Always enable transmit in YC$RESUME, the old version
had some checks that have been removed. This would show
up with a terminal line being hung in the XOFFed condition.

o On battery backup systems, check for power fail when setting
DMA on. If a power fail has occurred then the state of DMA/NODMA
will not be changed. The old version always set it to DMA.

o Some ports would hang in a state where all DMAs would timeout.
The Silo mode would operate correctly.

For OpenVMS VAX V5.3 - V5.3-x:

o Random extra characters are transmitted on terminal lines.
The characters are most often lower case "h". Care must be
taken not to confuse this problem with just random noise
causing extra characters. This problem is caused by noise on
one line generating characters on another line.

NOTE: This problem would only create parity errors on systems
with noisy lines.

For OpenVMS VAX V5.4 - V5.4-2:

o There has been a long outstanding problem with VAX 8800 type CPUs
with a UNIBUS. The problem is with the NBIB adapter. The adapter
has a problem with READ/MODIFY/WRITE instructions.


YIDRIVER:

o If a process that sets a READSYNC bit exits without resetting
the bit to NOREADSYNC, the port hangs until a "SET TERM
Txxx/NOREADSYNC" is issued to that port from another terminal.

o When a process is in the /READSYNC mode, the DMB32 may not
generate all the XONs and XOFFs automatically.


YFDRIVER:

OpenVMS VAX V5.1 - V5.3-x:

o Always enable transmit in YF$RESUME. The old version had some
checks that have been removed.

o Create a port routine to clear the XOFF state for disconnect.
This will clear the forced XOFF problem.

OpenVMS VAX V5.4 - V5.4-2:

o The YFdriver will report modem signals even when modem is turned
off. This is needed to keep the modem bits in the UCB consistent
with the device.

o There has been a long outstanding problem with VAX 8800 CPUs with
a UNIBUS. The NBIB adapter has a problem with READ/MODIFY/WRITE
instructions. The problem normally shows up as a fatal UNXIOINT
(unexpected I/O interrupt)bugcheck

NOTE: This ECO kit should not effect the normal operation of terminal
lines.

The following table correlates drivers, controllers and OpenVMS VAX
versions for which there are fixes in CSCPAT_0151:

ECO KIT ORDERING INSTRUCTIONS:

If after an evaluation you wish to obtain this kit, request it
electronically using the appropriate Advanced Electronic Services
(AES) Service Tool. If you are not familiar with how to request
kits electronically, open the DIA, WIS or DSNLINK database and
review the article entitled:

[AES] How To Electronically Request ECO (Patch) Kits Using Service Tools


INSTALLATION NOTES:

In order for the corrections in this kit to take effect, the system
must be rebooted. If the system is a member of a VAXcluster, the
entire cluster should be rebooted.
