I'm currently using ioct with TIOCGICOUNT on linux for retrieving counts of input serial line interrupts.

The counts are written to the serial_icounter_struct.

Most data fields are 32-bit integers.

What happens if a number of counts for a certain input line is greater then 32-bit integer value?

Does a system refresh counter on daily basis automatically?

Is there a way to reset a counter so that starts again from 0?
