- & UNICOM 2.0c Update from 2.0 and 2.0a
-
- * Full-up shareware release. All features are enabled.
- * Fixed! Save terminal type
- * Fixed! Efficiency calculation. I was too conservative.
- It was too low (in reality). Overhead bits
- (parity & stop/start) are now factored in.
- * Fixed! Various Modem setup radio buttons now remember
- their positions.
- * Changed: Add directory entry uses current baud rate
- * Changed: ZMODEM max allow errors extended from 5 to 12.
- * Fixed (?) You tell me: Some users reported:
- Unrecoverable Application Error. If this ever happens
- to you, please contact the author immediately.

- & Where is UCLIB.DLL ?
-
- The manual incorrectly refers to UCLIB.DLL which is not
- included in distribution. It should read UCLIB.EXE.
-
- & Hi Speed Error Correcting Modems
-
- Your modem should be set for hardware handshaking using
- CTS and RTS when using hi-speed.
-
- For 14.4k bps using USR HST, send AT &b1 &H1 &R2 before
- dialing. The system to be dialed should be set for
- 19,200 bps. The remote host must be another HST modem
- to support this.
-
- & Does the Screen layout look funny to you?
-
- Two screen areas are displayed at the same time:
-
- The scrollback and terminal screen. Both are displayed
- in contrasting colors. ANSI color will always default
- to Black Bkng and White Chars although the remote host
- will set the colors for you.
-
- Black and white terminal operation will set the terminal
- screen to the window color. The scrollback area (on
- top) will always be the inverse of the terminal screen
- color.
-
- For now the scrollback area is always displayed. This
- may become an user selectable option later.

-
- & Color Operation with Your Video Adapter
- UNICOM provides Color ANSI-BBS terminal emulation.
- This color capability has been developed and tested
- with color video adapters up to 640 x 480 resolution.
-
- If your video adapter is operating at resolutions above
- 640 x 480, screen performance may degrade especially when
- operating at higher baud rates.
-
- Should you encounter performance or reliability problems
- when operating UNICOM in color at 800 x 600 or higher:
-
- 1) Switch off the UNICOM color option in the terminal
- setup window and run exclusively in black and white.
-
- - or -
-
- 2) Install a lower resolution video device driver into
- Windows using the Windows Setup Utility.
-
- & Check your hardware BEFORE installation
- Unlike other Dos-based communication programs, UNICOM does
- not talk directly to your hardware. Instead, it uses the
- communication port driver built into Windows.
-
- Windows requires each device to operate using a unique interrupt
- setting. No two devices may be set to operate using IRQ 3 or
- IRQ 4 at the same time.
-
- Devices to watch for include: BUS MOUSE INTERFACE CARDS,
- MUSIC SOUND BOARDS, Option boards that include a Serial Port.
-
- Remove any TSR or special device drivers and reboot.
-
- If your machine locks, crashes or if UNICOM is unable to
- communicate reliably, check your hardware configuration FIRST.
-
- If you are a registered user, call for technical support after
- 6pm Pacific time.
-
- & Setting your Modem to Hang up FAST
- UNICOM will now drop the DTR line to your modem when
- attempting to disconnect a phone connection.
-
- To allow UNICOM to hang up quickly using this DTR drop
- method, you must provide this hardware signal to your modem
- using an RS-232 cable that supports pin 20. The modem must
- also understand that it is to drop the line upon loss of DTR.
-
- The modem modem init string should contain such a command since
- it is sent each time UNICOM is loaded. Consult your modem
- reference for the command specific to your modem.
-
- & Undocumented Host Mode Features
-
- Some host mode capabilities snuck into the software after the
- manual went to print. A (P)age operator menu selection
- was added to allow conversations with the user (sysop)
- operating the host computer.
-
- A bell will ring on the host computer and a message will
- be displayed announcing the remote user chat request.
- To answer the page, just select the Chat Mode item from
- the control menu. Don't leave host mode then go into
- chat mode, you may drop the phone line by doing so.
-
- When chatting is done, just unselect Chat. The remote user
- will be dumped back to a menu just as if nothing has
- happened.
-
- & YMODEM G Downloading Note
-
- Ymodem G seems to require that you start the sender
- FIRST, allowing a minimum of 5 seconds BEFORE you
- activate a download into UNICOM.
-
- & Lost Your Cursor?
-
- It is possible for the cursor to move above the top
- of your window when a screen erase is performed.
- To retrieve it, scroll the screen down to locate the
- top of the terminal screen.
-
- UNICOM does not scroll the window to follow the cursor
- in all cases.
-
- & Running UNICOM with Other Applications
- BE CAREFUL
-
- Dos applications will impair the performance of your Windows
- applications in the following ways.
-
- 1) If you are running in real mode and start a dos app,
- time critical Windows applications (such as UNICOM) will
- stop in their tracks. Time criticial operations like
- data transfers will 'Timeout'. When control returns to
- UNICOM after the Dos app is closed, any transfer in progress
- will likely have aborted.
-
- 2) If you are running Windows in standard or enhanced 386 modes,
- Your Windows applications will continue to run but may suffer
- performance losses since Dos applications receive time slices.
-
- Some Windows applications are unfriendly in the sense that they
- hold onto the CPU too long and starve other, more friendly
- Windows applications. A good example is loading a med-large
- spreadsheet into Excel. Depending upon your computer and drive,
- this could take more than 60 seconds.
-
- Excel holds on to this time and prevents other applications from
- running. If you just happened to be running a UNICOM data transfer,
- it will likely time out.
-
- The purpose of this topic is to make you aware that Windows has
- performance limits. By understanding them, you may be able to
- avoid problems such as these.
-
- & Using COM1 through COM4 under Windows 3
-
- UNICOM communicates to the outside world using the capabilities
- of the communication port built-in to Windows itself.
-
- Windows 3 provides support for COM1 through COM4. UNICOM allows
- you to 'request' access to any of these ports.
-
- If you have an AT or XT class of computer, access is allowed to
- at most TWO ports at any given time. These two ports must not
- share the same interrupt level.
-
- In other words, at most you can use one of the following pairs
- of ports:
- COM1 and COM2
- COM1 and COM4
- COM2 and COM3
- COM3 and COM4
-
- The following table lists the default base port and interrupt
- levels assigned for COM1 - COM4.
-
- DEFAULT DEFAULT
- DEVICE PORT ADDRESS INTERRUPT LEVEL
-
- COM1 3F8 IRQ 4
- COM2 2F8 IRQ 3
- COM3 3E8 IRQ 4
- COM4 2E8 IRQ 3
-
- Windows lets you change the BASE port address for any of these
- ports (see SYSINI2.TXT) but, unless you have an EISA or
- Microchannel system, the interrupt level cannot be changed from
- the defaults shown above.
-
- If you have COM3 and COM4 and it is not recognized by Windows,
- your BIOS may be at fault. The job of the bios is to instruct
- dos as to your hardware configuration upon each boot of your
- computer.
-
- To determine what serial hardware has been recognized by your
- bios, use a debugger like symdeb.exe to examine special
- memory addresses in your computer.
-
- Windows will blindly believe that hardware exists for any
- base port value placed in the following memory addresses:
-
- DOS ADDRESS PORT
- 0040:0000 - 0001 COM1
- 0040:0002 - 0003 COM2
- 0040:0004 - 0005 COM3
- 0040:0006 - 0007 COM4
-
- It is the job of your bios to determine the contents of these
- locations. If the bios is not doing its job, these addresses
- may be updated by an experienced expert. Some public domain
- utilities will also do this for you.
-
- If any of these address pairs are zero, no port is assumed.
- To check if Windows recognizes these addresses, select
- the 386 enhanced setup from control panel (if you have a 386
- or 486). All recognized ports will be listed.
-
- NOTE: COM3 and COM4 are not supported by Windows 2.x
-
- & Using External Protocols
- External protocols written for DOS may behave poorly in the
- Windows environment when entering and exiting these
- applications. Multitasking performance can be drastically
- reduced when executing DOS (external) applications using
- Windows versions 2 and 3.
-
- Use of external protocols with UNICOM is possible, but not
- recommended.
-
- & Where to find the Latest UNICOM
- The latest release of UNICOM can always be found on CompuServe
- in the library section within all Windows application forums.
- At the CompuServe prompt !, Type GO MSWIN or GO WINAPA.

- & PLEASE HELP DISTRIBUTE UNICOM
- UNICOM may be freely distributed according to the license
- agreement displayed upon activating UNICOM for the 1st time.
- This license can also be found in the online manual.
-
- If you like this program and wish to share it with others,
- feel free to upload it to your favorite BBS or computing
- service.
-
- & Please save your license number!
- You have just bought a UNICOM license and entered it into
- the registration window. Everything is fine, UNTIL you
- reinstall windows - then UNICOM acts as if it is not
- registered. The license in the Win.ini seems similar but,
- UNICOM does not like it. What will you do?
-
- PLEASE avoid this problem and save your original number
- for future use. It is printed on your receipt.
