Note2: When COM2 port is used for RS-232 flow control, i.e. RTS and CTS signals are used for flow control,

COM3 port will become incapable of being used.

Note3: When COM2 port is used for RS-422 flow control, please refer to the following COM3 Port signals table

for pin assignments. The signals, RTS+, CTS+, RTS- and CTS- shown in brackets are the signals used

for flow control.
