WHATSNEW.20 - Fixes, Changes, and new features in HST20
-------------------------------------------------------
Note: the last published release of the HST script was 1.8.
Release 1.9 of the script was never publicly distributed.
FIXES
- A number of cosmetic fixes were made to insure consistency.
- Unusually long timeout delays were shortened to more realistic
values.
- Default COM parameters are now set to 19200-N-8-1 upon exit,
and a message is displayed advising the user that the Qmodem
Alt-P command must be used to change these settings if they
are not the system's default. The Qmodem script language can
set communicaitons parameters unconditionally but cannot
determine their current values. Certain script operations
require a 2400bps serial rate, and previous versions of the
script left the serial port at the lower rate upon exit.
- Changes were made by USR within ROM level 964. Early 964
upgrades did not document certain 964 features, and these were
not implemented in release 1.8. All known 964 features
(specifically, s-register 15 settings) are in release 2.0
- The word "abort" was changed throughout the script to the word
"cancel" or "terminate" after I was told by well-meaning people
that computer or not, problem or not, DOS precedent or not,
this term was despicable.
- Certain portions of script code were relocated in an effort to
improve execution speed. Frequently-executed code should
always be located at or near the top of the script, something
I found out the hard way.
CHANGES
- Other than change in copyright and a couple minor cosmetic
changes, the biggest change to the HST18 code was the removal
of the PC option, used for HST setup for PCBoard 14.x
operations. HST17/18 have been criticized for not being
fully consistent with CDC's official PCBModem program. So as
to avoid conflict or misunderstandings, this option was
removed. The only official setup option is now QM, for Qmodem
4.0 originate / receive operations (Qmodem 4.0 has a built-in
Host mode and QM settings appear to work just fine).
NEW FEATURES
- Addition to S15 settings mentioned earlier in the fix section.
- Addition of S13 register settings as option 21 of main menu.
- Modem command files and external script programmability.
External files can now be used to store modem as well as
user-defined Qmodem 4.0 script commands, which will be
executed dynamically by HST20. This includes an AUTOEXEC-like
feature, which, coupled with the programmability feature of
the script, can be used for totally unattended script
operations. Operation of the HST20 script can be altered
externally via these command files. Read the documentation
for additional details.
