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.
