Setting Environment to Bug/Operating System
ENV [;[D]]
The Environment (ENV) command allows you to interactively
view and configure all Bug operational parameters that are kept in
Battery Backed Up RAM (BBRAM), also known as Non-Volatile
RAM (NVRAM). The operational parameters are saved in NVRAM
and used whenever power is lost.
Any time the Bug uses a parameter from NVRAM, the NVRAM
contents are first tested by checksum to insure the integrity of the
NVRAM contents. In the instance of BBRAM checksum failure,
certain default values are assumed as stated below.
The bug operational parameters (which are kept in NVRAM) are
not initialized automatically on power up/warm reset. It is up to
the Bug user to invoke the ENV command. Once the ENV
command is invoked and executed without error, Bug default
and/or user modified parameters are loaded into NVRAM along
with checksum data. The operational parameters that have been
modified will not be in effect until a reset/powerup condition.
If the ENV command is invoked with no options on the command
line, you are prompted to configure all operational parameters. If
the ENV command is invoked with the option D, ROM defaults
will be loaded into NVRAM.
