VXI:CONF:INF:ALL? Returns the static information about all logical
addresses. The information is returned in the order specified in the response to
VXI:CONF:LADD?. The information about multiple logical adddresses will be
semicolon separated and follow the IEEE 488.2 response message format.

:READ? VXI:READ? < logical_addr>,<register_addr> allows access to the entire 64
byte A16 register address space for the device specified by logical_addr. Since
the VXIbus system is byte-addressed, while the registers are 16 bits wide,
registers are specified by even addresses only. This method of identifying
registers follows the VXIbus standard format.

Comments • Specifying an odd register address will cause an error 2003,"Invalid word
address".
• Specifying a logical address not currently in the system will cause an error
2005,"No card at logical address".
• Logical_addr must be specified in decimal. Register_addr may be
specified in decimal, hex (# H), octal (# Q), or binary (# B).
• This command has been retained for compatibility with existing

command.
• Accesses are 16-bit non-privileged data accesses.
