Details

The RPL buffer keeps outgoing inband replies (messages). Your application adds inband replies to the RPL buffer with the sock.setsendinband method. Several inband replies may be waiting in the RPL buffer.

Older devices had smaller RAM sizes, so the value returned by this property was of the word type. On newer devices with larger RAM capacities, this property has the dword type. Inspect the property's declaration on the platform you are using to make sure you know its type.
