The possibility of leaving a modem connected permanently:
As you can see one of the serial ports is called "RS 232 / Modem". This port
allows the use of a modem to facilitate its set up. This port is optimised for use
with a modem but can still be used for normal communication use.
ATTENTION :
The RS 232 connector described above is replaced by the connector situated on
the right of the RJ45 connector in devices equipped with TCP/IP Ethernet cards.
This connector is thus inactive.
