-
- 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.
-
- * PortInfo will detect a Hayes ESP card (version 1 & 2), and a
- Practical Peripherals HSSP.
-
- * Several of the port conflict tests have been improved.
-
- * A new local-loopback test detects failed UARTs.
-
- * All utilities are "aware" of the SMC serial port (UART) problem,
- and use the prescribed method of control to avoid system lockups
- with the port.
-
- * Additional bonus utilities and and program controls for
- registered users.
-
- * Many other minor changes...please refer to the User Guide.
-
- Version 1.3 February, 1994
- ============================
- --------------
- -- Problems --
- --------------
- * Some network cards were interferred with by the PortInfo
- test resulting in a lockup after PortInfo completed running.
- Two changes in PortInfo address this problem:
-
- 1) There is a new command line option "/XIi" that you can use if
- you know which IRQ your network uses. This command line option
- forces PortInfo to eXclude Irq "i" from the test. For example, if
- your network card is on IRQ 5, then add "/XI5" to the command
- line. Use of this command completely resolves the problem.
-
- 2) PortInfo has also been changed to avoid the lockup condition
- if you don't specify the "/XIi" command option. Starting with
- version 1.3, PortInfo no longer causes a lockup, but you may lose
- your network connection. You canlog out and then back in to the
- network to re-establish your connection.
-
- * Under some circumstances, PortInfo would repeat message
- PI-3000 (a port address conflict message) when detecting two
- serial ports installed at the same address. Fixed!
-
-
- Version 1.2 December, 1993
- ============================
- --------------
- -- Problems --
- --------------
- * PortInfo would not detect a PS/2 mouse on an ALR EISA system. Fixed.
-
- * DOS_COM /n was broken by previous "fix". Unbroken!
-
-
- Version 1.1 November, 1993
- =============================
- --------------
- -- Problems --
- --------------
- * PortInfo failed to detect PS/2 mice. Fixed.
-
- * "DOS_COM /n /Aaaa" failed to install the port "n" at address "aaa"
- in the BIOS data area. Fixed.
-
- * The DOS_FMT command line was not parsed properly if the format was
- specified before the port ("DOS_FMT /n /Ffff" works,
- "DOS_FMT /Ffff /n" does not). Fixed.
-
- ----------------------------
- -- Changes / Improvements --
- ----------------------------
- * PortInfo automatically detects and tests any ports listed
- in the BIOS data area when no CTSCOMn environment variables are
- set for the ports.
-
- * The "Emulated UART" note was expanded to cover original 8250B UARTs
- installed in fast computers. This UART is too slow for the faster
- computer bus, and is occasionally detected by PortInfo as an
- "Emulated UART".
-
- * Removed "/Iii" from a startup error message. "/Iii" is not used by
- any current utilities.
-
- * The control utilities BUFFER, COM_BPS, COM_FMT, DTR, IRQ, RESETCOM
- and RTS will first attempt to use the standard and CTSCOMn port
- assignments. If these fail, then they will check the BIOS data area
- for a possible alternate serial ports installed by DOS_COM or
- other BIOS data area update programs.
