Parameter
Description
Addr.
Data type
Value range
Default
Unit
Wildcard char-
acter
This parameter is similar to the "don't
care character" parameter. The differ-
ence between this and the "don't care
character" is that all subsequent char-
acters, and not only one character at a
certain position, are disregarded until a
character pattern is found in the string
that follows the wildcard character pat-
tern. This character has the same
behaviour as the wildcard character for
the DIR command in the command line
interpreter under Windows.
