2.4.4 Understanding the Disk Operating System (DOS)
A computer user operates, communicates with and commands the computer using the computer's Disk
Operating System (DOS). DOS commands have special meanings to the computer.
Before you can use DOS commands, they must be either installed on your hard disk, or loaded into the
computer's RAM via your diskette drive. The table below lists the procedure to “Load DOS” if your com-
puter does not have a hard disk. This table assumes your computer has a diskette drive labelled A.
DOS version 3.2 or later is required to run RSS
. However, we highly recommend later versions, the later
the better, such as DOS 5.0.
Note: An intermittent serial bus error may occur when using DOS 4.01 - if after checking the communica-
tions between the computer and the radio you receive the same error, try a different DOS version.
DOS commands can be either upper case or lower case letters, it doesn't matter, but we show all DOS
command in upper case letters.
Table 2-5.
