HP OpenVMS Alpha Version 8.3 and HP OpenVMS Version
Networking Facilities
OpenVMS provides device drivers for all HP local area network (LAN) adapters listed in the LAN Options sec- tion of Appendix A of this SPD. Application programmers can use the QIO system service to communicate with other systems connected via the LAN using either Ethernet or Institute of Electrical and Electronics Engi- neers (IEEE) 802.3 packet format. Simultaneous use of HP Ethernet and the IEEE 802.3 protocols are sup- ported on any HP LAN adapter.
OpenVMS Alpha supports Ethernet, FDDI, Token Ring, and ATM for local area networks (LANs). OpenVMS for Integrity servers supports Ethernet only.
OpenVMS Alpha supports the standards defined by the ATM Forum’s LANE Version 1.0 specifications for LAN emulation over an ATM network. By implementing an emulated LAN over an ATM network, you enable a group of ATM stations to act like a traditional LAN. LAN emulated over an ATM network allows you to run your existing applications basically unchanged, while the computers on which your applications are running are connected to the ATM network.
OpenVMS supports the following networking products:
•HP TCP/IP Services for OpenVMS, the industry- standard set of protocols for interoperating between different operating systems
•HP
•DECnet, the DIGITAL Network Architecture, Phase
IV
These networking products are described in this SPD under Associated Products.
Terminal Server Products
HP terminal server products provide terminal server ac- cess to OpenVMS. When used in an OpenVMS Clus- ter environment, terminal servers distribute users across the available Alpha and Integrity server systems at login time.
OpenVMS can also establish a connection to other devices (such as printers) attached to such terminal servers.
Universal Serial Bus Support
OpenVMS supports the Universal Serial Bus (USB) technology. Support for the USB interconnect enables OpenVMS systems to connect to multiple supported USB devices using a single USB cable. OpenVMS sup- ports one USB keyboard and mouse on systems that are supported by OpenVMS and have USB hardware and a graphics controllers.
Beginning with OpenVMS version 8.3, HP OpenVMS I64 serial support is provided through the USB serial multiplexer (MUX). OpenVMS supports several generic chipsets which allow

OpenVMS provides a USB configration tool called UCM that can be used to track USB configuration changes like plug and unplug events. UCM can also be used to restrict the automatic addition of specific devices and classes of devices. The UCM event log is used by HP to help diagnose problems with USB devices.
AlphaServers
OpenVMS supports the fully qualified USB devices listed in the appropriate AlphaServer platform configu- ration and options web site:

OpenVMS Alpha USB support is limited to low and full speed devices only, and currently supports only the Al- phaServer ES47, ES80, and GS1280 systems.
Integrity Server Systems
Starting with OpenVMS version
Reliability
OpenVMS handles hardware errors as transparently as possible while maintaining data integrity and providing sufficient information to diagnose errors. The system limits the effects of an error by first determining if the error is fatal. If the error occurs in system context, the current OpenVMS system shuts down. If the error is not fatal, the system recovers actions pertinent to the error and continues the current operation.
In all cases, information relevant to the error is written to the error log file for later analysis. Hardware errors include the following categories:
•Processor errors. These include processor soft errors, processor hard errors, processor machine checks, and adapter errors.
