FIX: HYDRA-II  5.11 V=8&9
 
The following list contains descriptions of modifications and enhancements
made to the HYDRA-II microcode. Should you have any questions of comments
with respect to these changes, please contact JDS MicroProcessing Product
Support.

RELEASE 5.11
============

This is a maintenance release of HYDRA-II microcode. The majority of
changes and modifications in this release are transparent to the users.
Most of the modifications were made to HYDRA-II's channel microcode to
correct errors  in channel command processing. The changes that should be
noted are:

1.  Support has been added for the Rebus 3000 Data Entry keyboard. The new
terminal definition is named "DATA".

2.  In release 5.10 a bug existed in CHANGE CUU diagnostic. This has been
corrected.

3.  During execution of Hydrautl "Save" and "Load" commands, the HYDRA-II
reset would sometimes cause missing channel and device ends due to channel
commands being discarded during the reset. This has been corrected. Also
included are command chaining fixes.

4.  In addition to the new microcode included in this release, a new HYDRA
Utility tape has also been created. This tape, Distribution Tape A, has
two new Terminal Definitions added; IBM 3270 and IBM 3180. An additional
file has been added to the tape. This file provides the keyboard maps and
Hexadecimal keystroke sequence3s for the majority of the terminals HYDRA
supports. However, some of the terminal definitions included in HYDRA were
built by customers who did not provide JDS with a keyboard map. Therefore,
not all Terminal DEfinitions defined have the associated keyboard map
included in this file.

5.  The new Version 8 HYDRA Documentation does not include the definition
for the DSPLY and LOAD BAUD diagnostic.

Since HYDRA now supports 38.4k BAUD rates, it was necessary to limit the
range of BAUD rates being checked because attempts to synch at the faster
BAUD rates (19.2K & 38.4K) appear as line noise to the slower BAUD rates
(1200 &2400). The BAUD table was designed to keep the range of BAUD rates
being tested closer together. In this manner, devices that are running at
the slower BAUd rates can be assigned one BAUD table at slower speeds
(1200 2400 4800 9600 19.2K) and another table for the faster rates (4800
9600 19.2 38.4 9600).

6. The new Version 8 HYDRA Documentation does not include the definition for
the DSPLY and LOAD TIME diagnostic. This should be used in conjunction with
the AUDIT facility to provide the correct time and date on reports
generated. By using this diagnostic you can change the internal time
stamping routines of the HYDRA to reflect the current date and time.

If you want to configure a port as ONLINE with a fixed BAUD rate, you
specify "ALLOW DYNAMIC BAUD RATE?" to "NO" and create a BAUD table with
the specific speed you desire as the first entry in the table. When an
attention generating key (ENTER) is selected, the first BAUD rate entry in
the table is selected.

The next release of the HYDRA Reference Guide will contain this
information. The last changes included in the new HYDRAUTL tape were
corrections in the default configuration files to change the references
from EROM to NVMM.
