Virtual Serial Port

The Virtual Serial Port function is a bidirectional data flow of the data stream
appearing on the server's serial port. Using the remote console paradigm, a
remote user can operate as if a physical serial connection is present on the
server's serial port. There are three types of data that can appear on a ProLiant
server's serial port:
The Virtual Serial Port provides a Java™ applet that enables connection to the
server serial port. The Java™ applet provides VT320 terminal emulation to
access an application configured for the serial port.
Windows® EMS Console
The Windows® EMS Console, if enabled, provides the ability to perform
Emergency Management Services in cases where video, device drivers, or other
operating system features have prevented normal operation and normal corrective
actions from being performed.
iLO, however, enables you to use EMS over the network through a Web browser.
Microsoft® EMS enables you to display running processes, change the priority
of processes, and halt processes. The EMS console and the iLO Remote Console
can be used at the same time.
The Windows® EMS serial port must be enabled through the host system RBSU.
The configuration allows for the enabling or disabling of the EMS port, and the
selection of the COM port. The iLO system automatically detects whether the
EMS port is enabled or disabled, and the selection of the COM port.
iLO settings are being modified through XML scripting.
iLO firmware is being updated.
