        TROUBLESHOOTING TERMINAL INSTALLATION - MULTIUSER DOS

1. Make sure the user has the Multiuser DOS Business Update of
September, 1991. For upgrade information contact 1-800-NETWARE.

2. Cable is frequently a problem.  A 5-wire null modem cable is needed.
The pin configuration is shown on page B-3 of the Multiuser DOS User
Guide.  It is highly recommended that the protocol be DTR/DSR.

3. For troubleshooting purposes ONLY, the user could construct a cable
with the following configuration:

        25 pin PC end           Terminal end (DB25)

        Transmit    2  -------- 3     Receive
        Receive     3  -------- 2     Transmit
        Ground      7  -------- 7     Ground

Using this cable, and setting the protocol (both in SETUP and on the
terminal) to NONE, one will be able to see whether any signal at all is
going from the main CPU to the terminal.  (Protocol may be referred to
as Flow Control.)

4.  Another good test of signal transmission is to define the port into
which the malfunctioning terminal is plugged as a Printer/Aux port (so
the terminal is treated by the system as a serial printer), in SETUP.
Reboot, select the correct printer number (from another terminal) using
the PRINTER or PRINTMAP command on the working terminal, and type DIR >
PRN.  The directory should "print" on screen of the terminal in
question.

5. Refer to Chapter 3 in the Multiuser DOS User Guide for setup
specifications.

6. If a PC or terminal is having trouble at higher baud rates, set the
baud rate (in Setup and on the terminal/PC) to 9600.

7. In Setup, make sure that the question "Does this terminal support
graphics" is answered correctly.  For standard monochrome terminals,
such as a Wyse 60/150, the answer is NO.  For a Wyse 370 to support
graphics, its personality must be set to GR/CGA.  A PC in Terminal
Emulation mode can be configured for color graphics use, by selecting
Emulation=PC/CGA in PCTERM.
