This object is a single-value trigger used to cancel a GSM wake-up dial that's currently in progress on the router, initiated earlier via mstrGprsDial. An administrator writes abort(1) to this object when they need to stop an in-flight wake-up call attempt, for example because it was started by mistake or the target device is already reachable another way. For example, writing abort(1) to mstrGprsAbort would halt an ongoing wake-up dial before it completes or times out on its own.
