ESPS 3.2 HP Beta Release Notes
.sp
9/30/88 1.1
.sh 1 "Introduction"
.lp
This document provides notes relevant to the HP Beta release 3.2 of
ESPS.  Please read this document and the Installation Instructions
completely before installing this release of ESPS.
.sh 1 "Contents of this Kit"
.lp
The ESPS 3.2 installation kit contains magnetic media of the ESPS 3.2
distribution.  This is a complete distribution; it is not an update.
For HP systems, the only supported media at this time is standard 9
track tape at 1600 BPI, in \fItar\fR format.
.lp
If you do not already have ESPS the the kit also contains a User's Manual,
containing documents describing the use of the system and manual pages for
all programs, library functions and file types.  If you do have ESPS, then
the kit contains update pages for your User's Manual.  The documents
provided are important, and should be read by all users of the system.
They provide essential information about using and programming with ESPS.
.sh 1 "Differences Between 3.2 and 3.2 HP Beta"
.lp
The only difference between this 3.2 HP Beta distribution and the
previous ESPS 3.2 release for Sun, Masscomp, and Convex are changes to
support the HP 800 and 300 systems.   The HP systems don't have
\fIindex\fR(3) and \fIgetwd\fR.  These were added to the library.
.sh 1 "Graphics on HP Systems"
.lp
Graphics on HP terminals or workstations is not supported by this
release.    Most of the ESPS plot programs can produce Tektronix
compatible output, so if your terminal is Tek 40X0 compatible, then you
can plot.   If you use IBM compatible PCs for termanals with the HP,
contact us and we can supply a public domain Tektronix emulator the PCs.
.lp
The first non-beta release of HP ESPS will support HP terminals.
.sh 1 "Hardcopy of Graphics"
.lp
The ESPS plot programs can produce output for the Imagen laser printer
using its Tektronix emulation mode.   If you have another type of
printer or plotter that can plot tektronix plots streams then you should
be able to use it as we use the Imagen.  If you use a postscript based
printer (such as the Apple LaserWriter) we can supply a public domain
tektronix to postscript emulator.   Call us if you want it.
.lp
If you use a HP Laser Jet, we can provide a GPS to HP raster converter.
This allows our plot programs to work with the HP printer.  It is slow,
since a large bitmap is downloaded to the printer.  Contact us if you
want this.
.lp
To adapt another type of plotter to the plot programs, look at the install
script under \fIesps_plot\fR.   Call us if you have
questions.   In the next major release, we are going to provide a better
way to specify the type of hardcopy plot device in the install script.
.sh 1 "Data Acquisition"
.lp
This version of ESPS does not directly support data acquisition (speech
input and output) on HPs.
This package does include the source code to the speech
input and output programs used on ESPS Masscomp systems.   If you have
data acquisition hardware, you might be able to modify these programs
for your hardware.  The speech input program is called \fImcplay\fR and
the speech output program is called \fImcrecord\fR.
.lp
If you have another means of data acquisition that results in a binary
file (of 16 bit integer data) you can use the ESPS program \fIbtosps\fR
to turn that file into an ESPS sampled data file.   You can also use
\fItestsd\fR with the -a option to produce an ESPS sampled data file
from an ascii file.
.lp
The ESPS program \fIbhd\fR can be used to remove the ESPS header and
leave behind just the binary data from an ESPS data file.   In the case
of sampled data files, you can convert to the correct data type with
\fIcopysd\fR first.
.sh 1 "Known Problems"
.lp
The following problems are known in the ESPS HP beta kit.   These will
be fixed in the first non-beta release.   Please report any other
problems found.
.np
The program \fIlpcsynt\fR produces sometimes fails.
.np
The standard Unix program \fIdiffmk\fR is called by the installation
script.  On HP systems, \fIdiffmk\fR will complain about \fBif syntax\fR
if one of the two files doesn't exist.  This is the case the first time
each program is installed.  On other Unix systems, a more reasonable,
but harmless error message is produced.  No harm is done and the
complaints should be ignored.
.np
The \fB-o\fR option on \fImlplot\fR doesn't work on some HP systems.
