This read-write enable/disable object controls whether periodic statistics are collected from this ComPort, defaulting to enable for two-way ComPorts and disable for telephone-return ComPorts, per the description. An admin uses this to reduce polling overhead on devices where the collected stats wouldn't be meaningful, such as telephone-return units. For example, an admin leaves hcxStuStatsCollect at its telephone-return default of disable since periodic RF stats aren't relevant for a device using a phone-line return path.
