The devices that are listed here are those devices that may be accessed by
the PADS Program during normal program operation.  Each of these devices
must be set to an ON-LINE status, and associated with an I/O port.

The status of the device can be a Y for ON-LINE, or N for OFF-LINE.  If a
device is set to OFF-LINE, it will not be accessible during normal program
operations.  To modify the settings, use the left and right arrow keys to
move over to the column to be modified and enter the values.

Each device can be assigned to I/O Port LPT1 - LPT9, COM1 - COM9, or PRN.
