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:

Windows® EMS console

Linux user session through serial tty (ttyS0)

System POST dialog (if BIOS serial console redirection is enabled)

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.
