MS-DOS Commands and the Equity LT
Your MS-DOS manual describes all the commands on the
MS-DOS diskette that you can use on the Equity LT. Three
commands described in the manual are not on your MS-DOS
diskette: HELP, ROMBIOS, and SYSTAT. These files are on
your reference diskette. If you want to use them, be sure to
insert the reference diskette in the drive or log on to the
directory on your hard disk where they are stored.
If you want these files to be on your MS-DOS diskette or
in a particular directory, use the COPY command to copy
them.
Additionally, you may find that a particular MS-DOS
command does not work on your Equity LT; this is because of
the computer’s hardware. For example, you cannot use some
parts of the MODE command because they have to do with a
monochrome monitor.
Using the backlit screen with memory resident
programs
If you use memory resident programs such as the popular
desk top accessories or the MS-DOS KEYBxx commands, you
may find that you cannot turn on the screen’s backlighting
once it has automatically turned itself off. If this happens, save
any data files you are working on and reset your computer.
You can prevent this problem from occurring by using the
Epson LIGHTON utility (on your Reference diskette). First
load your memory resident program and then enter the
LIGHTON command (type LIGHTON and press
Enter); this
order is very important. Another solution is to select no time
limit for the backlight period in the Setup program. (See
Chapter 1 for instructions.)
If you use memory resident programs that interfere with the
backlit screen’s operation, it is best to install them with a batch
file that also includes LIGHTON as the last command.
