Es: Enable Spu Status Display; He: Print Help Menu - HP 3000 Series Handbook

For HP Internal Use Only
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.
