Signal Names
Signal names used for the FP's serial interface are designed to match the
pin order used on most PC serial interfaces, so that a straight cable can be
used to connect the two. Therefore, connect each pin's signal to the same
signal name on the PC connector.
For example, pin #2 'RD' should be connected to the 'RD' input terminal
on the FP's connector.
Refer to section "2-4 Option Cable Pin Diagrams" for information about each
signal's direction.
