DOS
JK microsystems’ controllers use XDOS, a compact operating system for embedded applications.
The XDOS command structure is nearly identical to MS/PC DOS version 3.3. The switches for
the DIR command have been changed and expanded. XDOS does not support redirected input or
output with the use of < and >, but does support pipes ( | ). None of the external DOS commands
are available due to size constraints. XDOS does not support installable file system functions.
XDOS Command Reference
In the list below, XDOS commands are followed by a function description and their format
including available parameters and switches. Items in boldface type must be entered. Capitals or
lowercase letters may be used. Items in italics are parameters. Those in boldface italics must be
entered, those in [ ] are optional. All switches are optional. They are shown as [/X]. Spaces and
punctuation are to be included. An ellipsis ... following items means that you may repeat the
items as often as needed. Do not enter the ellipsis or the square brackets. Most XDOS commands
allow the use of wildcards in filenames and extensions. When wildcards (?=one character, *=any
character or characters) are used, the command is executed once for each matching file.
Common parameters are:
[
d:
]
drive specification - a letter followed by a colon (:), e.g. A:, if no drive is
specified, the default drive is used.
[
path
]
the path DOS must take in traveling from one directory to another; directory
names are separated by a backslash (\).
[
filename
] up to 8 characters used to name a file.
[
.ext
]
a three character extension may be added to a filename; an extension is
separated from a filename by a period.
