Using PC Cards (continued)
Problem
After you load your Novell network
software, you use a network PC card and
run an application that does not work
properly after making a system call.

Solution
Your Novell network software may have modified the
COMSPEC environment variable to add a drive specifier to the
path. However, DOS needs COMSPEC to find the
COMMAND.COM file, which must be loaded for DOS to
execute system commands. The reader uses ROM DOS, which
expects COMSPEC to be set to:
comspec=command
To eliminate this problem, run the INITENV utility before you
log onto a NetWare server. INITENV.EXE is on the reader's
drive C and Application companion disk 3. Create a login batch
file similar to this one:
@echo off
c:\initenv
e:\login %1 %2
set comspec=command
Use the new login file instead of your Novell login file when
you log the reader onto the server. If you do not run
INITENV.EXE before logging in, your DOS environment table
will be corrupted and cause your JANUS application to fail. You
can set COMSPEC correctly to fix part of the problem, but you
must boot the reader to clear embedded garbage characters
from the environment table.
To check COMSPEC, type set and press
variables are displayed. If COMSPEC was set to anything other
than COMMAND, it has been changed by the login process.
