- GENERAL HINTS AND TIPS FOR TROUBLESHOOTING LANTASTIC Z
-
-
- If you are experiencing difficulties in making two computers communicate using
- LANtastic Z, there are a few basic "rules of thumb" to follow. The first of
- which is to eliminate all possible sources of interference.
-
- 1> The file CONFIG.SYS in both computers should be as simplistic as
- possible :
-
- Example CONFIG.SYS -
-
- FILES=50
- BUFFERS=32
- LASTDRIVE=Z
- FCBS=16,8
- DEVICE=C:\DOS\SETVER.EXE [for DOS 5.0 ]
- INSTALL=C:\DOS\SHARE.EXE [for DOS 4.01 ]
- DEVICE=C:\DOS\ANSI.SYS [optional ]
-
- 2> The file AUTOEXEC.BAT in both computers should be temporarily renamed
- so as not to be executed at boot-up. This can be done with the command
-
- REN AUTOEXEC.BAT AUTOEXEC.SAV
-
- 3> Re-boot both computers. At the DOS prompt type PROMPT $P$G (so you can
- see which directory you are working in).
-
- 4> Use only the cable supplied by Artisoft (included in the LANtastic Z
- package)*, and connect the two computers together.
-
- *If you are attempting to establish communications via modem connections, please
- refer to Testing Communications Using The Modem Connections on the following
- pages.
-
- TESTING COMMUNICATIONS USING THE PARALLEL CONNECTIONS
-
- SPECIAL CONSIDERATIONS :
-
- 1> The parallel port being used must be capable of bi-directional
- communications. Generally, very inexpensive parallel cards do not have
- this capability.
-
- 2> IBM PS/2 Microchannel computers generally will not communicate using
- LPT2, due to the fact that both parallel ports LPT1 & LPT2 share IRQ 7
- (interrupt request channel).
-
- 3> Some laptop computers have the ability to control an external floppy
- disk drive using the parallel port. On these machines, the parallel
- port must be set for PRINTER. The documentation for these machines can
- be confusing in the fact they state that FDD is for bi-directional
- communication, and PRINTER is for uni-directional communication.
- Ignore this documentation.
-
- 4> Multi-function I/O cards which have a parallel port, serial port, game
- port, and disk controller on one board, generally do not have bi-
- directional communication capabilities, therefore will not be able to
- communicate using LANtastic Z.
-
- TEST PROCEDURE :
-
- 1> Type CD\LANTASTI <return> at both computers
- 2> Type PPORT PORT=LPTx <return> at both computers.
- 3> Type AILANBIO <return> at both computers.
- 4> Type LANCHECK MAIN <return> at the main computer
- 5> Type LANCHECK REMOTE <return> at the other computer.
-
- At the MAIN computer, you should see a screen resembling this :
-
- A# NAME NODE NUMBER MINUTES RUNNING STATUS ERROR (INDEX)
- _______________________________________________________________________________
- 0 MAIN 00008293312 3 LOCAL 0 (0%)
- 0 REMOTE 00009344872 2 ACTIVE 0 (0%)
-
- At the REMOTE computer, the screen should look the same, with the NAMEs reversed.
-
- If these are the results you obtain from this test, the two computers are
- communicating properly. Restore the original AUTOEXEC.BAT, and CONFIG.SYS files, reboot the
- computers, and run STARTNET P. If the two computers will not communicate,
- isolate the item which is causing the interference by removing one line at a
- time from the AUTOEXEC.BAT file, and re-trying until successful.
-
- If either computer only sees itself as LOCAL, chances are the parallel card in
- that computer is not capable of bi-directional communications. Replace the
- parallel card and re-test.
-
- If both computers only see themselves as LOCAL, verify that the cable is plugged
- into the correct LPT port by plugging the cable into the other port (while
- LANcheck is running). If that does not effect anything, both computers may have
- non bi-directional parallel cards. Replace both parallel cards and re-test.
-
-
- TESTING COMMUNICATIONS USING THE SERIAL CONNECTIONS
-
- SPECIAL CONSIDERATIONS :
-
- 1> Whenever possible, use the COM1 or COM2 ports for testing purposes.
- COM3 and COM4 share the same IRQ channels with COM1 and COM2, possibly
- causing a hardware conflict.
-
- 2> Some IBM PS/2 microchannel computers have weak serial ports, thus
- rendering them incapable of establishing communication with the serial
- connections. However, this does not mean that all PS/2 computers will
- exhibit this incompatibility.
-
- 3> Multi-function I/O cards which have a parallel port, serial port, game
- port, and disk controller on one board, generally will not support
- communication using LANtastic Z.
-
- TEST PROCEDURE :
-
- 1> Type CD\LANTASTI <return> at both computers.
- 2> Type SPORT PORT=COMx <return> at both computers
- 3> Type AILANBIO <return> at both computers
- 4> Type LANCHECK MAIN <return> at the main computer
- 5> Type LANCHECK REMOTE <return> at the other computer
-
- At the MAIN computer, you should see a screen resembling this :
-
- A# NAME NODE NUMBER MINUTES RUNNING STATUS ERROR (INDEX)
- --------------------------------------------------------------------------------
- 0 MAIN 00008293312 3 LOCAL 0 (0%)
- 0 REMOTE 00009344872 2 ACTIVE 0 (0%)
-
- At the REMOTE computer, the screen should look the same, with the NAMEs reversed.
-
- If these are the results you obtain from this test, the two computers are
- communicating properly. Restore the original AUTOEXEC.BAT, and CONFIG.SYS files,
- reboot the computers, and run STARTNET S. If the two computers will not
- communicate, isolate the item which is causing the interference by removing one
- line at a time from the AUTOEXEC.BAT file, and re-trying until successful.
-
- If either computer only sees itself as LOCAL, either the cable is plugged into
- the wrong port, or the serial card is incompatible. Plug the cable into the
- other serial port (if there is another serial port) while LANcheck is running.
- If that does not effect anything, replace the serial card, and re-test.
-
-
- If both serial ports are verified as working, and communications cannot be
- established, there is a possibility of a defective cable. Contact Artisoft
- Technical Support, LANtastic Z department for further instructions.
-
- TESTING COMMUNICATIONS USING THE MODEM CONNECTIONS
-
- SPECIAL CONSIDERATIONS :
-
- 1> Whenever possible, use two alike modems (same brand, same model).
-
- 2> Whenever possible, use the COM1 or COM2 ports for testing purposes.
- COM3 and COM4 share the same IRQ channels the COM1 and COM2, possibly
- causing a hardware conflict.
-
- 3> Both modems must be configured the same. Set the following modem
- switches (where applicable) according to the users manual for your
- particular modem. These switches typically may be set through software
- using any terminal emulation program, and utilizing the AT command sets
- Some modems have hardware switches (either DIP switches or internal
- jumper sets) that may be set.
-
- A. Carrier Detect (CD) follows true carrier (not always on)
- B. Auto Answer (AA) set to ON
- C. Data Terminal Ready (DTR) set to state 2
- D. Clear To Send (CTS) and Ready To Send (RTS) set to ON -or-
- E. Modem set for Bi-Lateral CTS/RTS flow control
- F. Data Set Ready (DSR) set to ON
- G. Data Compression set to OFF
- H. Transmission speed (BAUD rate) set the same on both modems
-
-
- TEST PROCEDURE :
-
- 1> Type CD\LANTASTI <return> at both computers
- 2> Type MPORT PORT=COMx BAUD=xxxx <return> at both computers
- 3> Type AILANBIO <return> at both computers
- 4> Type REDIR SERVER <return> at the main computer
- 5> Type SERVER <return> at the main computer
-
- At the computer that will be initiating (dialing) the call, perform the
- following steps :
-
- 1> Type Z_MGR <return>
- 2> Use the cursor keys, highlight TERMINAL EMULATION, hit <return>
- 3> At the terminal emulation screen, type ATDTxxxxxxx <return>
- (where xxxxxxx = phone number)
-
- At this point, the modem will dial the number, the other modem will answer and
- report CONNECT 2400 (or 9600 if using 9600 baud modems). If the error message
- "Modem not online, cannot communicate with COM port" occurs, the switches
- described in SPECIAL CONSIDERATIONS above are not set properly.
-
-
- Approximately every 2 to 4 seconds, the terminal emulation screen should show
- some unreadable graphic-type characters followed by "group-LANtastic| SERVER".
- At this point, tap the F4 key, then tap the ESC key to go to the DOS prompt,
- and type REDIR REMOTE. After the redirector installs, you should be able to go
- to the NET menu, login to the SERVER computer, and redirect drives and printers
- to the server.
-
- After completing this test, remember to ABORT the Network Connection using the
- Z_MGR menu.
-
- If, in terminal emulation mode, the SERVER's name is visible, but the login
- attempt returns a "Cannot locate network name" error, generally the modem's flow
- control is set incorrectly. Set both modems to use a different form of CTS/RTS
- flow control, and re-test.
-
- If, in terminal emulation mode, the only thing visible is a series of zeroes and
- right pointing triangles, the flow control again needs to be adjusted to a
- different form of flow control.
-
- If, in terminal emulation mode, there are no readable characters at all,
- generally one of the modems is running at a different transmission speed (baud
- rate) than the other. Verify modem configurations are set the same on both
- modems, and re-test.
-
- If none of the above symptoms occurs, and no communication can be established,
- call Artisoft Technical Support, LANtastic Z department for further assistance.
-
-
- After successfully completing this test, the two computers are communicating
- properly. Restore the original AUTOEXEC.BAT, and CONFIG.SYS files, reboot the
- computers, and run STARTNET M. If the two computers will not communicate,
- isolate the item which is causing the interference by removing one line at a
- time from the AUTOEXEC.BAT file, and re-trying until successful.
