Only changes after the sys.buffalloc method is used. "Preparatory" methods like ser.rxbuffrq do not influence what this property returns.

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