- Introduction
-
-
- Until recently, networking was expensive and complicated, beyond the reach of
- the small computer user. Now, even if you have just two PCs and a printer, U-
- Net lets you enjoy the savings, enhanced performance and extra productivity
- that networking provides.
-
-
- U-Net is the first complete network available via shareware, and also the first
- network that can be installed by a computer novice. U-Net allows small
- businesses to install the network and see the advantages of sharing software,
- data files and printer between any two IBM or compatible computers without
- major financial investment.
-
-
- U-Net is a Server/Workstation based network. This means that one of the
- computers (generally the fastest with the largest or only hard disk drive) is
- set up as the Server and the other computer becomes the Workstation. The
- software, datafiles and printer attached to the Server computer can be shared
- concurrently while the Server computer is being used.
-
-
- Note the Server computer cannot access the Workstation's drives or printer. If
- information on the Workstation needs to be shared, it should first be copied up
- to the Server computer.
-
-
- U-Net's biggest benefit to users is "ease of use". Installation should take you
- less than five minutes. The cable simply connects between the parallel ports of
- the two computers. No new knowledge is required as U-Net uses standard DOS
- commands. The hard disk drives and the printer attached to the main (server)
- computer are accessed as if they were physically attached to the other
- (workstation) computer.
-
-
- We take this opportunity to welcome you as a U-Net user and as such can assure
- you of our ongoing support and further development of the product. We will of
- couse keep you informed as these enhancements and upgrades become available.
-
-
- We wish you well using U-Net II and hope you find it to be of good value.

- This second release of U-Net, U-Net II offers support for DOS 5, most OEM
- versions of MSDOS and disk partitioning software. Also the printer
- redirection (to share the server's printer) is activated now using a
- pop-up menu. The programs are no longer device drivers that need loading with
- the CONFIG.SYS file, but can be run after the systems are booted. Both
- programs also now can be unloaded when not required.
-
-
- Please be sure to keep your Registration Number available and quote this on
- all technical support correspondence. Should you have chosen the LanDapter
- option then you will be advised the technical support phone line for contact.
-
- We appreciate your support of our product and the Shareware concept. Your
- registration enables us to further develop U-Net and other innovative products
- and provide them to you at affordable prices.

-
- Technical Requirements
-
-
- * Computers must be IBM or compatibles. They can be any mix of PC, XT, 286 AT,
- 386, 486 or PS/2 Microchannel computers.
-
-
- * The main (SERVER) computer must have a hard disk drive. The other computer
- (WORKSTATION) must have at least one floppy disk drive.
-
-
- * Each computer must have a standard parallel port available. If there is none
- free then you may have to add a second or third parallel port.
-
-
- * Any printer that you wish to share has to be connected to the SERVER's first
- parallel port (LPT1).
-
-
- * It is recommended that the SERVER computer have a minimum of 640Kb RAM.
-
-
- * It is recommended that you use MSDOS 3.3 or later and the same version of
- DOS on both computers.
-
-
- * The maximum recommended cable length between the computers is 10m (30 ft).

-
- U-Net II Software Installation
-
-
- The following files should be on your Installation Diskette;
-
- UNET.EXE
- ATTACH.COM
- README
-
-
-
- Insert the Installation Diskette in Drive A of the computer designated to
- become the SERVER (the computer whose hard disk drive(s) and printer you wish
- to share) and type in;
-
- A: <Return>
- COPY UNET.EXE C: <Return>
-
-
-
- Now insert the Installation Diskette in the other computer (called the
- WORKSTATION) and type in;
-
- A: <Return>
- COPY ATTACH.COM C: <Return>
-
-

-
-
- Cable & Port Connections
-
-
- U-Net requires the linking together of the two computers using standard
- Parallel Ports with a special cable. You can either make this cable yourself
- as described below, or order a special Adapter (see registration options on
- page 2) that connects with a standard printer cable to make the connection.
-
-
- We recommend a maximum cable length of 10m (30ft).
-
-
-
- Use data grade cable, 11 wires with shield and male DB-25 connectors. Wiring
- is as follows;
-
- Pin 2 to Pin 15
- - 3 -- --- 13
- - 4 -- --- 12
- - 5 -- --- 10
- - 6 -- --- 11
- - 10 -- --- 5
- - 11 -- --- 6
- - 12 -- --- 4
- - 13 -- --- 3
- - 15 -- --- 2
- - 25 -- --- 25
- (Also connect both pins 25 to shield)
-
-
-
- Port Connection
-
- Be sure to connect the cable to LPT2 if there is more than one parallel port
- in the computer.
-
-
-
- Page 6
-
-
- Using U-Net II
-
-
- Simply type on the SERVER;
-
- C: <Return>
- UNET <Return>
-
- Within 5 to 8 seconds you will get the screen message;
- Installed for Port XXX
- (XXX being the port U-Net uses)
-
-
- Ensure the cable is connected between the Parallel Ports on the computers. The
- cable should be connected to LPT2 if there is more than one Parallel Port in
- the computer.
-
-
- Type on the WORKSTATION;
-
- C: <Return>
- ATTACH <Return>
-
-
- You will notice on the WORKSTATION that extra virtual drives have been added
- (being the SERVER'S drives). They can be accessed as though they are
- physically present in the WORKSTATION Computer using normal DOS commands.
- They will appear as the next logical letter(s) after any local WORKSTATION
- hard drive(s).
-
-
- Both the SERVER and the WORKSTATION retain all of the features they had as
- standalone computers, however now the WORKSTATION can concurrently access the
- SERVER'S hard disk drive(s) and printer.
-
-
- To access the SERVER'S printer from the WORKSTATION press the CTRL key and
- Right Shift key simultaneously and select on the pop-up menu to redirect
- printing to the Server's printer. Use this menu to change back printing to the
- local printer should you wish to do this. The WORKSTATION printing normally
- defaults to it's local printer on booting up.
-
-
- To STOP the network running (i.e. unload U-Net);
-
- On the SERVER Type in UNET/U <Return>
- On the WORKSTATION Type in ATTACH/U <Return>
-
-
- U-Net gives you the ability to share software and datafiles when using LAN
- (local area network) or multi-user versions of your application software by
- running SHARE (a DOS program included in DOS 3.3 and later). This gives you
- file and record locking facilities.
-
- Page 7
-
- Trouble Shooting
-
- * It is recommended that you use MSDOS 3.3 or later and the same version of
- DOS on both computers.
-
- * The cable must be connected to the LPT2 Port if there is more than one
- parallel port in the computer.
-
- * U-Net software takes 20Kb (approx) of the SERVER'S first 640Kb RAM and
- 16Kb on the WORKSTATION Computer. It is recommended that you have 640Kb
- or more RAM in the SERVER computer.
-
- * Only use SHARE on the SERVER computer when using multi-user or LAN versions
- of your application software as it takes up memory and will slow performance
-
- * Some "non-compatible" IBM clones; some Tandy models, Amstrad, etc are not
- fully compatibile and will not work.
-
- * Mixtures of DOS between SERVER and WORKSTATION can give problems.
-
- * Computer Games and Formatting of Diskettes should be avoided on the
- SERVER Computer while U-Net is running as this can cause problems.
-
- * Number of files open in the Config.Sys file on the SERVER may need
- increasing as it must open enough files for the WORKSTATION also.
-
- * If WORKSTATION programs are halted abnormally then it may be necessary to
- reboot the SERVER to ensure any open files are closed.
-
- * If using different screen types (mono and color) then a sub-directory on
- the SERVER with different configurations of the software may be required.
-
- * Sometimes PATH commands and AUTOEXEC files on the WORKSTATION need
- modifying to allow for files residing on different virtual drives.
-
- * There may be a conflict in the SERVER between the U-Net software and some
- other TSRs running. If this occurs you should ensure that U-Net loads
- first which may solve the problem.
-
- * Cables of too great a length or inadequate quality can give problems.
-
- * ERROR - SERVER not responding, U-Net II installation cancelled.
- indicates that either the SERVER is not running the program UNET or the
- cable is not properly connected. Re-plug the cable and re-run the programs.
-
- * If the appended virtual drives do not appear to be mapped correctly then the
- LASTDRIVE parameter should be set in your CONFIG.SYS file on the WORKSTATION
- e.g. LASTDRIVE = G (allows drives up to G:)
-
- * If having the cable connected appears to interfere with either computer
- booting up, then boot both computers before connecting the cable or ensure
- the SERVER program UNET is running before booting the WORKSTATION computer.
-
- * Transfer speed with U-Net is dependent on the speed of the slowest computer.
- For best performance fast 286 or 386 computers are recommended.
