For
HP
Internal Use

If background processing
of
I/0
commands received
in
the
remote
port's
IO_COMMAND
register is
not
supported,
the
port
must
be
placed
in
a busy
state.
This means
that
any
commands received
at
that
time
must
not
be
executed. Instead,
the
driver
that
issued
the
command should
be
notified
that
the
command
was
not
executed because
the
port
was busy,
but
that
it
will be executed as soon as
the
port
is available
to
the
driver again. Only one
command
will
be
buffered
in
this
manner. If a second command is
written
over a
command
that
was
not
completed due
to
the
port
being busy, undefined things
may
occur.
On initial power
up
the
remote configuration defaults to:
• Remote
Operator
Access Disabled (see
DR
command)
• Mode = Multiple
•
Password=
None
• Password
Faults=
3
• Remote Copy Screen = Disabled
The
following two
paragraphs
describe how
the
mode
and
password fault
parameters
are used
to
enhance console security.
Access Mode:
Single-
The
remote user only has
three
attempts
to
enter
the
correct password. If
the
user succeeds,
the
remote console session is begun
and
remains
until
the
user disconnects
or
until
the
user is
disconnected by
the
local console
operator.
If
the
user fails,
the
line is disconnected. In
either
case, after
the
disconnection,
the
line is dropped,
the
remote console is disabled,
and
the
port
becomes a normal session
port.
To use
the
remote
port
as a remote console once again,
the
remote console capability
must
be
re-enabled by
the
local console.
Access Mode:
Multiple-
The
remote user has
three
attempts
to
enter
the
correct password. If
the
user succeeds,
the
remote console session is begun
and
remains
until
the
user disconnects
or
until
the
user is
disconnected by
the
local console
operator.
If
the
user fails,
the
line is disconnected. After
disconnection,
the
line is dropped
and
becomes available for future calls
through
the
modem.
If
the
user does
not
succeed
in
providing
the
correct password, a password fault count is
increased,
the
caller is disconnected,
and
the
line is dropped.
When
the
password fault count
exceeds
an
operator
set
limit,
the
remote
operator
access capability is disabled.
The
modem
port
may only
be
used as a normal session
port
until
the
local console
operator
re-enables
the
remote capability by using
the
ER
command.
