Er: Enable Remote Operator Access - HP 3000 Series Handbook

For HP Internal Use Only
Dl: Disconnect Remote Console
Definition:
This command causes the lAP to initiate a modem disconnect sequence on the remote support
modem if it is being used as a remote console. After executing this command the lAP
de-asserts the modem control lines, thus forcing the modem to "hang up" the telephone line.
The remote support modem port is then no longer connected as a mirrored console, and the
local console port becomes master.
If the remote access mode (see ER command) was set to be single, remote operator access
is disabled and must be re-enabled by using the ER command to once again allow remote
operator access. If the remote access mode was set to be multiple, the lAP will connect the
next incoming call on the remote support modem port to the lAP as a remote operator
connection.
Valid From: Remote Modem Port
DR: Disable Remote Operator Access
Definition:
This command disables remote operator access on the support modem port. If an operator is
connected as a parallel console at the time this command is executed, the remote console is
disconnected. Any future incoming calls to the remote support modem will be handled by the
system as a user session. If remote operator access was already disabled when this command
is executed, this command has no effect.
If background command processing for busy ports is not supported on the l/0 card, the
following applies: When switching from Remote Operator Enabled to Remote Operator
Disabled, any buffered commands posted to the host's remote modem port should be
completed and the Estat field of that port's lO_STATUS register set appropriately. This
indicates to the driver that the port is no longer busy. A "ready to connect" connection status
will be sent to the driver.
Valid From: Local Console Port, Remote Modem Port
OS: Disable SPU Status Display
Definition:
Disable display of the system's OSTAT and hex display to the console terminals when in
console mode. See ES: Enable SPU Status Display command.
Valid From: Local Console Port, Remote Modem Port
ER: Enable Remote Operator Access
Definition:
This command, available only on the local console, enables remote console access to a user
on the modem port and configures the connection security parameters. The mode parameter
establishes how many times the remote user may connect, disconnect, and reconnect the
remote console before remote console access is automatically disabled. The password
parameter is set by the local console operator and stored in nonvolatile memory. The
password fault parameter sets the number of password faults allowable (3 password attempts
per fault) before remote console access is automatically disabled.
