CTS Serial Port Utilities, Version 3.4 HISTORY.DOC
This file contains a synopsis of all changes in the CTS Serial Port
Utilities up to and including this release.
Version 3.4 January, 1996
=========================
--------------
-- Problems --
--------------
A "phantom port" would be tested in rare situations. Fixed!
One type of port would occasionally report missing a few IRQs. Fixed!
----------
-- New --
----------
World Wide Web Home Page and FTP downloading is available from:
http://www.comminfo.com (world wide web) or
ftp://ftp.comminfo.com/users/www00402 (current shareware versions)
Version 3.3 October, 1995
=========================
--------------
-- Problems --
--------------
A program lockup would occur with BIOS_Fix in a few situations. Fixed!
Version 3.2 September, 1995
============================
----------
-- New --
----------
Added detection for RPI modems - these are displayed as "RPIFAXModem"
on the PortInfo summary screen.
Support is now available in the "Benchmarks and Standards" forum on
CompuServe. GO BENCHMARK to join the forum and look for us in the
diagnostics section.

A program lockup would occur in a few situations. Fixed!
Version 3.1 August, 1995
=========================
It never fails. As soon as a new version gets released...
The IRQ used by some new, inexpensive modems was not always
detected by PortInfo (any version). Fixed!
Version 3.0 July, 1995
========================
----------
-- New --
----------
* Our phone numbers are changing! Please note our new area code is
770! Details are at the end of this file.
* Added the BIOS_FIX utility. BIOS_FIX ensures correct installation and
initialization of the serial ports when run from the AUTOEXEC.BAT file.
The registered version verifies the Windows serial port setup as well.
* Added the ResetMod(em) utility. ResetMod(em) performs a complete reset
of a modem - doing everything possible (via software) to obtain or
regain control of a modem. Very handy for use with internal modems when
a power-off is the only other answer. An optional setup string can be
added to ResetMod(em) if a specific modem setup is required.
* Added the HangUp utility. HangUp will do everything possible to force
the modem to hang up the phone line. Very helpful to run after programs
that do not properly hang up the modem.
* Added support for two new UART types to PortInfo: the 16650 from
StarTech and the 16750 from Texas Instruments. These are
identified as the "ST-650" and "TI-750" on the PortInfo summary
screen respectively. Buffer-Trigger levels are also properly reported
for the receive buffer.
* Added new conflict tests:
- Specific test for a Mouse/Modem conflicts;
- A Long Test option for finding difficult to detect conflicts.
* Added a new message type: "For Your Information". This message
type will replace Warning messages, when appropriate (for
example, when a Com4 port cannot be used in a computer).
* PortInfo will perform a complete analysis of the serial port
configuration and verify that Windows is set up correctly. Specific
changes, if needed are reported. (Registered Versions)
* A more complete interrupt scan. PortInfo detects the IRQs in CONSTANT
use by devices that will definitely conflict with communications. These
are listed and then avoided by PortInfo unless run with the /NoScan
option.
* A modem identification report that displays the modem identification
command results (registered versions).
* Introducing OEM versions of PortInfo - please see OEM.DOC or contact
CTS for details.
----------------------------
-- Changes / Improvements --
----------------------------
* The BIOS "sliding port" report has been greatly simplified. Individual
ports that are mis-assigned are now noted on the summary screen.
* Many other minor changes...please refer to the User Guide.
--------------
-- Problems --
--------------
* Version 2.3 "over-fixed" the display card not detected problem -
detecting cards that were not there! It's really fixed now!
* Port address conflicts between a T/Port and other serial ports was not
detected. Fixed!
Version 2.3 February, 1995
============================
--------------
-- Problems --
--------------
* Some newer 8514/A display cards were not being detected. Fixed!
* PortInfo would "lock up" when running with one newer type of 8514/A
display. Fixed!
* An interaction between a Prohance serial mouse driver and
PortInfo could cause a false report of a "T/PORT" port type. Fixed!
----------------------------
-- Changes / Improvements --
----------------------------
* A new conflict test can often detect when both a "Com4" serial port
and an 8514/A display are installed. If the conflict is not detected,
the port type is shown as "Display" on the summary screen.
* If a serial port interrupt is intermittant, the IRQ will be displayed
on the summary screen along with an asterisk ("*") to indicate an
IRQ was detected, but having a problem.
* All utilities will leave the video mode alone - if you run DOS in
50 line mode, then it stays in 50 line mode!
* Some error messages have been updated...
Version 2.2 December, 1994
============================
--------------
-- Problems --
--------------
* PortInfo would detect an internal loopback failure on a couple
of brands of internal modems which do not support the loopback
test. Fixed!
* The Find_Com utility (Professional versions) did not allow
excluding an address range from the serial port search. Fixed!
Version 2.1 November, 1994
============================
--------------
-- Problems --
--------------
* PortInfo would terminate with a "divide by zero" error on a
computer with no serial ports installed. Fixed!
----------------------------
-- Changes / Improvements --
----------------------------
* ESP detection is now optional - a potential existed for a
system lockup on a few computers. Run PortInfo with the command
line switch "/ESP" to enable ESP detection.
* Log files and printer output now have graphics characters
"filtered" so that the reports are more attractive.
* Error messages about interrupt conflicts now include the IRQ
number whenever possible.
* New packaging reduces international AIR shipping rates.
* Now accepting American Express.
Version 2.0 October, 1994
===========================
--------------
-- Problems --
--------------
* One type of port conflict could cause PortInfo to lock up. FIXED!
----------
-- New --
----------
* All utilities now operate within a Windows or OS/2 DOS box.
* PortInfo now identifies which ports have modems and FAXmodems,
also showing the FAX class(es) supported by the modem.
* A new "short report" format option quickly shows current ports,
IRQs, BIOS settings, and port types.
* A new "install BIOS addresses" option allows PortInfo to update
the BIOS data area with the actual port addresses.
* PortInfo now automatically detects active network connections and
avoids interfering with the connection.
*
