Description: The number of times the signal has changed from 'on' to 'off' or from 'off' to 'on'.
What is rs232InSigChanges?
Counts how many times this input signal has toggled between on and off, letting an admin spot a flapping modem or handshake line (e.g. a rapidly incrementing DCD change count suggests an unstable physical connection).
