Configuring the IM4 as a Serial Module
12 IM4 Module Integration Guide
These pins are a carryover from the PC card interface. These signals are
mutually exclusive for any PC card application. In order for the IM4 to
operate in Serial mode, you must ground all three of these signals, which
keeps the card from driving signals defined for serial operation into a
regular PC card socket.
