Async Word Length, Elastic Store disabled, and Anti-Streaming

2.2.3 RS232/V.35 Shunt
Data terminal equipment with either a RS232 or V.35 interface can
be connected to the DB25 connector on the backplane of the rack.
The 16-pin shunt on the back of the MT56DSU-R board must be
placed in either the "V.35 position or the "RS232" position. The
interface is determined by the position of this 16-pin shunt. The
MT56DSU-R is shipped from the factory with the 16-pin shunt in the
RS232 position.
