Using the Optional Serial Signals
Signals GPIO 1 to 6 can be used as GPIO or Serial Port control signals DTR, DSR and DCD.
To configure signals DTR, DSR and DCD, place a jumper between JP4 and JP5 for that signal, as shown
in Figure 5.
To select the GPIO signals, place the jumper between JP3 and JP4. The GPIO signals are available at JP7.
Standard serial RS-232 signals are available on the DB-9 connectors J2 and J3 for serial ports 1 and 2,
as shown in Figure 6.
