What does rOM.E mean?

This error indicates that the remote display terminal has detected an internal Read-Only Memory (ROM) anomaly, typically identified by a checksum calculation failure. This points to a critical internal hardware malfunction within the display terminal's firmware storage. The terminal's basic functionality may be compromised.
