A recent change claimed to fix an off-by-one error in the OOB-port completion handler, but instead introduced such an error. This could specifically led to modem-status changes going unnoticed, effectively breaking TIOCMGET. Note that the offending commit fixes a loop-condition underflow and is marked for stable, but should not be backported without this fix.
