ANSWER
This is caused by the DEBUG port not being configured correctly for use with a temperature controller.
To use a FlexTest SE Controller with a temperature controller, configure the
DEBUG serial port as follows:
498.96 Processors
1. Access the Model 498.96 Processor circuit card in the controller’s chassis.
Caution: Please remove power from the controller before adding or removing hardware.
2. Locate switch S3 (Figure 1).

MVME 5100 Processors
1. Access the Model MVME 5100 Processor circuit card in the Controller’s chassis.
Caution: Please remove power from the controller before adding or removing hardware.
2. Locate switch S3 (Figure 3).
