For HP Internal Use Only
Valid From: Local Console Port, Remote Modem Port
RS: Reset SPU
Definition:
This command resets the system, lAP I/0 card excluded, by deasserting the backplane
POVv'" _ON and SEC_QN signals. For multiple bus systems, a reset signal is provided on the
support cable. The lAP firmware controls the length of time that POW _ON and SEC_ON
are forced to the off state and the support cable RSTSYS_L signal is asserted. The reset
condition should be held for a minimum of 5 milliseconds.
In order to ensure proper functioning of this command, the processor must mask off the reset
from the backplane.
The proper SPU reset sequence is as follows:
• Determine that the Operator really wants to reset the system by requiring that the operator
confirm that a system reset is desired.
• Firmware notifies the operator that the system reset has been successful.
• Reset the I/ 0 functions on the lAP I/ 0 card.
• The AP is placed in Console Mode to prepare for rebooting the system.

Local Console Port, Remote Modem Port
SE: Enter Session Mode On Remote Port
Definition:
This command may only be entered from the remote port and allows the user to leave control
mode and enter session mode. To re-enter control mode, the user need only exit the user
session. The lAP will reconnect the operator as a parallel console after the driver releases the
connection.
After entering the SE command, the Access Port should send a "ready to connect" connection
status to the driver through the IO_DATA_IN_IOE7 FIFO. Assuming that no other error
precludes clearing error information in the IO_STATUS register, the Se bit should be cleared
and 0 placed in the Estat field of the IO_STATUS register for port 7.

SO: Security Options
Definition:
This command enables three features that can be independently enabled. The features are:
• Non-Activity Timer
• CMD_RESET Monitor
• Restricted Command Set
You must enter a configuration password to enable any of these features.
Non-Activity Timer. When the Access Port firmware is in the CONTROL mode and the
Non-Activity Timer is enabled (ON), the Access Port firmware monitors the console terminal
for input. If no input is received in three minutes, the Access Port firmware exits the
CONTROL mode and returns to the CONSOLE mode.
