RS-485 Directional Control
Many device drivers use the RTS signal to switch between receive and
transmit mode. Some third party communication drivers expect the
directional control to be automatic. The PA2 PowerStation does not
automatically switch between modes and depends on the driver to use the
RTS signal to perform this operation.
