You may be mistaking that for the Morse (Telegraph) used between wheelhouse and engine room to communicate engine demand. The 'morse' in this case is the name of the cable used to connect the two telegraph devices together - basically a sheathed steel wire physically connecting the two handles on the telegraph unit.

The wheelhouse would crank one handle to the required speed/direction and the engineroom would 'reply' by copying the handle position to acknowledge the call.

This was necessary as there is no direct connection between the wheelhouse and the engine (like a throttle cable and carburettor!) - the engineers had to make the necessary adjustments to the main engine in regard to speed and rotation direction.
