Set Environment to Bug/Operating System
ENV [;[D]]
The ENV command allows you to interactively view/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 parameters are loaded into
NVRAM along with checksum data. If any of the operational parameters
have been modified, the new parameters do not go into effect until a
reset/powerup condition occurs.
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.
The parameters to be configured are listed in Table A-1.
