VM600 NETWORKING INTRODUCTION AND OVERVIEW
Midnight Commander is included in CPUM firmware version 075 or later in order to provide
an easy way to work with a CPUM’s configuration files. The Midnight Commander command
(mc) can be used in a terminal emulation session to manually provide all of the operations
that are automatically supported by CPUM Configurator.
As Midnight Commander is included in the firmware running on the CPUM card
(see Table 1-1), vi is the only alternative that can be used to edit configuration files directly
on the card (see 1.3.4 vi editor). However, an FTP client can be used to download the
configuration files so that they can be edited locally on a computer, then uploaded to the
CPUM card.
1.3.4 vi editor
vi is a text editor program that supports the editing of text files.
vi is included in all versions of CPUM firmware in order to provide an easy way to work with
a CPUM’s configuration files. The vi command (vi) can be used in a terminal emulation
session to manually edit configuration files directly on a CPUM card.
As vi is included in the firmware running on the CPUM card (see Table 1-1), Midnight
Commander is the only alternative that can be used to edit configuration files directly on the
card (see 1.3.3 Midnight Commander). However, an FTP client can be used to download the
configuration files so that they can be edited locally on a computer, then uploaded to the
CPUM card.
NOTE: Refer to the VM600 networking manual, edition 6 (or earlier), for additional
information on the vi text editor.
