# Using ATPMODE.EXE

Use ATPMODE.EXE to change the software operating mode of your AT Plus Ringnode from its normal mode to AT mode. To change the software operating mode from AT mode back to normal mode, use ATPMODE.EXE again.

| If your Ringnode is password protected, make sure that you type the correct password.

Running ATPMODE.EXE

When you run ATPMODE.EXE use the command-line options. To do this, type at the DOS prompt:

`ATPMODE <command-line options>`

Each command line must begin with the ATPMODE command, followed by the /IO= option, which specifies the I/O location of the Ringnode whose software operating mode you want to change.

For example:

`ATPMODE /IO=0A20 /MODE=normal`
Changes the mode of the Ringnode at I/O location 0A20 to normal mode.

`ATPMODE /IO=0A20 /MODE=at`
Changes the mode of the Ringnode at I/O location 0A20 to AT mode.

`ATPMODE /IO=0A20 /LIST`
Displays the current software operating mode of the Ringnode at I/O location 0A20.
