MMEMory Subsystem
MMEMory Subsystem
The purpose of the MMEMory subsystem is to provide access to mass
storage devices such as internal or external disk drives.
HP ESA analyzers use two types of mass storage devices:
• 3.5 inch disk drive (high density, 1.44 MBytes formatted) designated
“A:”
• Part of flash memory and treated as a device designated “C:”
The MMEMory command syntax term
<file_name>
is a specifier
having the form: drive:name.ext, where the following rules apply:
•
“drive” is “A:” or “C:”
• “name” is a DOS file name of up to eight characters, letters (A-Z, a-z)
and numbers (0-9) only (lower case letters are read as uppercase)
• “ext” is an optional file extension using the same rules as “name,”
but consists of up to three characters total
Catalog the Selected Memory Location
:MMEMory:CATalog? <drive>
where “drive” is “A:” or “C:”
Lists all files in the specified drive. The return data will be of the
format: <mem_used>,<mem_free> {,<file_listing>}
Each <file listing> indicates the name, and size of one file in the
directory list: <file_name>,,<file_size>
Example:
Catalog drive C:
, which is in instrument memory:
CATalog? "C:"
