Optional.
-script
Specifies an optional script string of expect-send pairs to be
sent over the line. This must be the last option in the
command.
If a send word is empty, i.e. if it contains single quotes (
‘‘
),
nothing will be sent until the expect word is received.
For a login sequence, you can use the words
$(USER)
and
$(PASS)
. They will be replaced by the arguments specified in
the
-user
and
-pass
options, respectively.
If the string does not include an escape code, a carriage return
character will be appended automatically at the end of the
string. Valid escape codes are:
\r
(carriage return),
\n
(line
feed) and
\t
(tab).
At the end of the script, the AXIS 240 will enter the
negotiation phase.
