- SIGNIFICANT CHANGES in This Release versus Earlier Version 3.3x and 3.4x.
-
-
- * Version 3.5 supports multiple servers. (For A+ and E+ II, not for I+)
-
- * The server station(s) sharable hard disks or RAM disks increased
- from two to four (C: , D: , E: , and F:).
-
- * User group applications had been re-defined.
-
- * Eliminated conflictions between network interrupt and compiled
- BASIC programs(ie. INT 3F is changed to INT 7AH).
-
- * "LASTDRIVE =" command on the REMOTE's config.sys file can be up to "I".
-
- * Detailed discrepencies from release 3.40 manual are listed below.
-
-
- 1) TOPSHARE.EXE
-
- When you upgrade your system to use version 3.5 software from versions
- 3.4x or earlier, you HAVE TO GO THROUGH <I>INITIALIZATION procedures again.
- That is to input your superuser, shared resources, and user accounts again.
- If you decide to use more than one server in the system, you need to do the
- initialization procedures as you have done on the first server station.
- Also additional server stations are subject to the same requirements as your
- first server, i.e. hard disk, enough memory, and CONFIG.SYS file. With this
- multi-server function, you can start the system from any server station.
- Then at the other server stations, you can choose it to be a server by
- "topnetf" or a user station by "topnetr".
-
- 2) TOPSPOOL.EXE
-
- For sharing the printer(s), the spooling work now has been assigned to
- the server station. Therefore, the user who requests a printer and the printer
- that to be requested have to log on to the same server station.
-
- A new TopSpool option is supported from TOP-NET version 3.50 :
-
- "Set TopSpool Priority"
-
- This is designed for sharing Laser printers or high capacity buffer's printers.
- The command format for setting TopSpool Priority is :
-
- C> topspool /t h ; set TopSpool Priority to High
- C> topspool /t n ; set TopSpool Priority to normal
-
- To let a PRINTER SERVER more fast, we suggest you set TopSpool priority to
- HIGH on that PRINTER SERVER and let that PRINTER SERVER on the DOS prompt.
-
-
- 3) CHANGE OF USER GROUPS AND FILE ATTRIBUTES
-
- We have consolidated user groups from 50 group levels into 8 groups. The
- new group numbers are 0,1,2,3,4,5,6,and 7. A user can belong to one or more
- groups, and the superuser(s) belong to all groups by default. The new file
- attributes consist of 8 group read/write permissions and a file owner number.
- (Please see TOPSTAT <A>ttribute function from server station or TOPATTR from
- user stations). For example, a file named TESTDATA.LAB has such attributes :
- rwr-r-rwrw----r- 005; which means this file has read/write permissions to
- group number 0,3,and 4; read-only permissions to group number 1,2,and 7; and
- denied access to group number 5 and 6. Only the superuser and the file owner,
- which is user number 5, have the right to change file attributes for this file.
- The group assignment is still done at superuser's User Account Maintenance.
-
-
- 4) Enable/Disable File Server's read/write protection attributes.
-
- From version 3.50, the TOPPRO can be used to enable or disable File
- Server's Read/Write protection attributes. If you activate File Server with
- Read/Write protection attributes DISABLED, this will have better
- performence of File Server but all TOP-NET's Read/Write protection
- attributes and LOCK/UNLOCK commands are become meaningless. (But DOS SHARE
- Record lock function still keep in effective.)
-
- *****************************************
- * CONFIG.SYS file for the File Server *
- *****************************************
-
- For the File Server, the new suggested value in the FILES= command on
- the CONFIG.SYS file is 255. Please refer to page 3-4 of the Top-Net
- Operation Manual, and create your CONFIG.SYS file for the File Server
- to contain at least following two command lines:
-
- BUFFERS = x
- FILES = 255
-
- The value for the BUFFERS command should be NO LESS than 40. The
- suggested value 255 is the maximum number of file handles that the File
- Server allows to be concurrently opened by all Remote stations.
-
- Please refer to the IBM DOS 3.1 Reference Manual page 4-7 and 4-22
- respectively for the BUFFERS and FILES commands.
-
-
- *********************************************
- * CONFIG.SYS file for all Remote Stations *
- *********************************************
-
- The LASTDRIVE command within the CONFIG.SYS file can be set to 'I'.
-
- Although we recommand the number of files to be opened is 20, the real
- limitation at remote station is 150 files. Due to the limitation at server
- station file handle can not be greater than 255 files, we hope that you may
- keep total files to be opened under a single server to be lower than 255 files.
- On this Version 3.50, you MUST MAKE SURE YOUR "FILES =" COMMAND ON THE
- CONFIG.SYS FILE IS LESS THAN 150 for all Remote stations.
-
-
- ***************************************
- * AUTOEXEC.BAT file for File Server *
- ***************************************
-
- From version 3.50, the start-up routine has eliminated many prompts than earlier
- versions. The AUTOEXEC.BAT can be greatly simplified as :
-
- topnetf UUU PPP
-
- Where UUU is the superuser's name, and PPP is the password.
-
-
- ***********************************
- * AUTOEXEC.BAT file for Remotes *
- ***********************************
-
- For version 3.42 and earlier, the TOPNETR.EXE would prompt following
- message when you logon to the network :
-
- >USERNAME please :
- >PASSWORD please :
-
- From version 3.50 and onward, another prompt will be displayed and ask
- the user to enter the File Server' station address. This will enable
- multiple File Servers can be actived on the TOP-NET.
-
- An example of AUTOEXEC.BAT file for the workstation as following :
-
- topnetr UUU PPP N
-
- Where UUU is the user's username, PPP is the password and N for
- the File Server's station address.
-
-
- *********************************
- * TOPPRINT.COM & PRNSHARE.EXE *
- *********************************
-
- Since these two utilities are no longer supported as from version 3.40,
- please ensure to delete from your AUTOEXEC.BAT file the TOPPRINT command
- if it was set therein for execution of the earlier versions. Also, in
- lieu of the PRNSHARE.EXE, now please use following new commands for
- printer sharing function:
-
- New Old command now obsolete
- ------------------ -------------------------
- TOPSPOOL /S ON PRNSHARE ON
- TOPSPOOL /S OFF PRNSHARE OFF
-
-
- ************************************************
- * Very Important Notes for All Top-Net Users *
- ************************************************
-
- When using some "single-user" packages (e.g., WordStar 2000, PE2...) on
- the Top-Net, you must pay close attention to the problem of conflicts
- caused by temporary file names.
-
- For instance: When editing any existing file in WordStar 2000 on a
- Remote Computer, at least four temporary files will be created on the
- File Server's hard disk. These are called OUTPUT.$$A, GOBACK.$$A,
- BLOCK.$$$, and DELETE.$$$. There will be a problem if another Remote
- user is also running this same package from File Server and working on
- the same subdirectory as you are. These temporary files created by you
- and another Remote user will have the same names. To avoid this, you
- must work on a different subdirectory.
-
- *********************************
- * Limitation on using TOP-NET *
- *********************************
-
- In the following situations, the File Server will stop serving the
- network for Remote stations.
-
- 1. Using DOS "TYPE" command on the File Server to display text file and
- press the <CTRL>S or <CTRL><Num Lock> keys to hold the display.
- 2. Using DOS "COPY CON file" command on the File server to create a file.
- 3. The re-direction for keyboard and display are not supported on this
- version.
-
- ***********************************
- * MS-DOS 3.2 Utility APPEND.COM *
- ***********************************
-
- Due to internal programming conflicts, the MS-DOS 3.2 APPEND.COM is not
- supported on the File Server. PLEASE DO NOT INSTALL it ON THE FILE
- SERVER. This utility is, however, still supported on the Remote
- stations.
-
-
- *****************
- * TOPMAIL.EXE *
- *****************
-
- When you SEND a mail to "ALL" users, it does not function properly.
- This internal bug will be resolved on version 4.0.
-
- *****************
- * TOPTERM.EXE *
- *****************
-
- This optional utility is not supported on the current version of the
- Top-Net diskette. However, an enhenced version will be ready when
- version 4.0 is released.
-
- ************************
- * TOPSPOOL vs TOPMAP *
- ************************
-
- Either one of these functions may change the printer selection. However, it is
- recommanded to use TOPSPOOL for printer selections, for it will give you more
- options on the printer or printing functions you will need.
-
- ***************************************************
- * Monitor Compatibility for TOPLOOK and TOPSHOW *
- ***************************************************
-
- On CGA and EGA monitors, the TopLook and TopShow functions are now fully
- compatible in both Text and Graphics modes.
-
- Text-only screen transfers can be made even when different PC's in the
- network are running different monitor systems (e.g., one system running
- CGA, another running EGA and a third one Hercules).
-
- For Graphics screen transfers, all systems involved in the screen
- transfer must operate under the same monitor system.
-
- ************************************
- * Automatic Time & Date Download *
- ************************************
-
- When you log your remote station onto Top-Net network system, the TIME
- and DATE from the file server is automatically downloaded into the
- station. Thanks to this convenient feature, a remote station is still
- able to have the network synchronized time-and-date function even
- without having being equipped with its own real-time clock.
-
-
-
- FOLLOWING NOTES are FOR SYSTEM PROGRAMMERS:
- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
- *********************
- * INT 1C Problems *
- *********************
-
- Some software packages, such as GWBASIC ver 2.02 or earlier, force the
- INT 1C (timer interrupt) function to stop. Running such softwares on the
- File Server will cause the File Server to stop to serving all Remotes.
- Running them on a Remote will cause that Remote to loose the ability to
- respond to the TOPLOOK, TOPTALK, TOPSEND, TOPTERM, and TOPSHOW functions.
-
- ******************
- * LOGON Status *
- ******************
-
- For system programmers who desire to confirm that a station has properly
- logged onto the network, the system will now return a code at the AL
- register:
-
- 0 = Logon OK 1 = Logon Error
-
- Please refer to the DOS function 4CH & 31H for DOS batch file
- applications using this return code.
-
-
- ****************
- * HANDLE.COM *
- ****************
-
- This program lets system manager to monitor up to 20 stations open file status.
- Each station will display up to 20 files being opened.
