Serial Port Control
JP4 (DIS_RS232) on the processor module is don’t care when the
module is plugged into the MDS-GP board. The console RS-232
driver U1 is always disabled as the –DIS_RS232 signal is
grounded by MDS-GP board via JP2-50.
JP3(DIS_IrDA) on the processor module must be removed to allow the
MDS-GP board to control the IrDA module. If this jumper is installed,
IrDA on the processor module is always disabled.
Jumper J2 Signals
Enable only one serial port function per interface (COM1 or COM2).
