New Features and Enhancements
Release 2.0.9 contains improvements to existing functionality found in Release 2.0. The
improvements are in the following areas:
• Command Line Interface (CLI)
• Network Processor Software
• Low-Speed Line Card
• LightStream’s Operating System (LynxOS)
• LightStream’s Trucking Software
• LightStream Congestion Avoidance Software
• LightStream’s Test and Control System (TCS)
• LightStream’s Line Card Flash Code
The only change in functionality is that the modem and terminal ports on the switch card no longer
support the BREAK detection mechanism. The user must configure the proper baud rates for local
and remote (modem) access.
