This read-only Counter tracks the number of received packets with frame alignment errors on the UART port since it was last enabled. It helps an administrator diagnose a faulty serial cable, connector, or clocking mismatch, since alignment errors typically indicate the receiver is not correctly framing incoming bits. A steadily climbing kxuartAlignmentErrors count on one port while others stay at zero would point the technician toward a bad cable on that specific UART link.
