From: Marcin Tomczak <marcin.tomczak@xxxxxxxxx> >From Richard Boyd: "No task timeout timer reduced from 20 to 2 This timer controls how long the SCU hardware will hold open the TX side of the connection before sending a DONE. The timer allows the hardware to attempt to optimize the DONE/CLOSE behavior to allow for new COMMAND IU to be posted. In practice closing the connection quicker is better."
