RIS—Reset to Initial State
This control function causes a nonvolatile memory (NVR) recall to occur. RIS replaces all set-up features with their saved settings.
The terminal stores these saved settings in NVR memory. The saved setting for a feature is the same as the factory-default setting, unless you saved a new setting.
It is recommended that you not use RIS to reset the terminal. You should use a soft terminal reset (DECSTR) instead. RIS usually causes a communication line disconnect and may change the current baud rate settings. When performing a RIS, the terminal sends XOFF to the host to stop communication. When the RIS is complete, the terminal sends XON to resume communication.
