COMMERCIAL USES OF THE HST SCRIPT

The series of TLX_HST Telix Scripts may not be used for
marketing, demonstrations, advertising, problem diagnosis or
correction OR ANY COMMERCIAL or Business purposes by modem
manufacturers, their agents, dealers, resellers, or any company
or individual involved in the sale, marketing, or maintenance of
modems or other computing devices.  Commercial and/or business
uses of the TLX_HST script(s) requires formal licensing of this
product.  To obtain a commercial-use license for the TLX_HST
script(s), the author may be contacted at the address shown at
the end of this document or on one of the Bulletin Boards listed
at the end of the TLX_HST.1ST file included with this package.


TELIX RELEASE DEPENDENCY

This script will operate with TELIX 3.12 (and later
releases of TELIX).  Due to Telix Salt Script Language
dependencies, Release 2.1 of this script WILL NOT OPERATE under
pre-3.10 releases of Telix. It will also run under 3.11 as well.


OPERATIONAL SUMMARY

TLX_HST.SLC is intended as a configuration and setup help for the
USR HST modem, and although it facilitates much of the modem's
setup tasks, some knowledge of the HST's operation and
technology is required, as well as a basic understanding of
computer communications.

If you are using TLX_HST to set up your USR Courier HST for use
with Telix 3.12 or PCBoard 14.x, two menu options (TX and PC)
will perform all firmware configuration, leaving physical switch
changes up to the user (but correct switch settings are
displayed as part of the script's operation).

TLX_HST automatically detects the ROM release level of your modem.
If your USR HST modem is at ROM level 964 or 144x TLX_HST will allow
you access to special advanced functions on various menus.
These menu functions accesse HST features only available in
964 & 144x-level modems, such as data compression (MNP level 5),
settings for the new S-register 15, 4800/7200/9600/14400 link rate
settings, and the new modem configuration screen.  Advanced
Functions are NOT available for ROM releases prior to 964.


SETTING UP THE HST FOR TELIX OPERATION

Although TLX_HST eases the setup tasks, it can't do it all.  It is
likely that you will need to change the modem's switches from
their default factory settings to the setup recommended in the
menu's TX or PC options.  Unfortunately, TLX_HST can't quite
"reach out and touch switches"; you must do this yourself.  The
script makes you aware of this requirement.

Another very important part of the modem setup is the
configuration of Telix itself.  With release 3.1x of Telix,
this is done with the ALT-O command, which updates the
Telix configuration file. Later in this document there will be
some information to help you select the proper Telix
configuration parameters for the HST modem.

I recommend that you keep your HST manual handy while you
experiment with the script.  Bug reports or suggestions for
changes or improvements should be reported to the
Rose Media BBS in Toronto.


FRIENDLY WARNING

TLX_HST can make permanent changes to the modem's internal
configuration.  Once a setting has been changed, writing the
change to Non-Volatile RAM (NRAM) implements the change until
that setting is changed and written to NRAM again.  Changes to
NRAM are maintained even when the modem power is OFF.  If you
have a working set of modem settings and wish to experiment, do
not copy the changes to NRAM.  The next hardware reset or
power-off / power-on sequence will re-establish the last NRAM
settings.  A description of the HST's basic
internal operation is included in this document; you may wish to review it
to gain a better understanding of the modem's settings.


NRAM NOTES TO PCBOARD USERS

PCBoard software insists on having total control over modem
answer operations following RING detect.  To comply with this
requirement, TLX_HST sets the RAM value of register S0 to zero to
disable automatic call answering. This script also indicates
that switch 5 be left in the DOWN (ON) position, which disables
automatic call answering and leaves this feature entirely under
software control.



SUPPORT

I will attempt to correct problems with this script, as well as
keep it current with releases of the HST's firmware and Telix
software only as time allows.  This is a personal effort which I
am sharing, but for which I receive no remuneration (except from
commercial users of the script).  Please make no unreasonable
demands for support, especially for things that are not broken;
you got this for free and if it does not perform as you would
like it to, you have a God-given right not to use it.  You may
also chose to alter the script to meet your unique requirements.
If you do so, please do not distribute the modified version
under its original name.  You may contact me on a number of
bulletin boards, a list of which is contained towards the end of
the TLX_HST.1ST file included in this ZIP archive.



HST MODEM SETUP UNDER Telix 3.12

Setting up your modem for Telix use is quite simple.  In the Telix
configuratin (ALT_O), make sure that the following parameters are
specified:

MODEM & DIALING OPTIONS

Init String:         ATZ~~~AT&B1^M
Hang Up String:      ~~~+++~~~ATH0^M
Dial abort string:   ^M
Drop DTR to Hang Up: on

Note: Use of the ~ as delay character and ^M as carriage return
will insure proper script operation under Telix release 3.12.


TERMINAL OPTIONS

Baud:         34800
XON/XOFF:     off
CTS/RTS:      on
DSR/DTR:      off    (NOTE: if DSR is on the TLX_HST will hang!)


DIALING DIRECTORY ENTRIES

Set the baud rate, for dialing directory entries that support another
USR HST modem at the other end, to 38400 baud for the best speed.


That's it.  proper switch settings are:

1,2,6,7,10: UP
All others: DOWN





INTRODUCTION TO THE HST MODEM

This document discusses some of the unique features of the HST
modem and gives more specific information on using the HST with
Telix 3.12 for Bulletin Board operations.  It is not deeply
technical, but major differences between the HST and other, more
conventional modems are covered.


HIGH SPEED PROTOCOLS AND MODEM COMPATIBILITY

The HST is fast, which is probably why you bo
