Thanks. I already had troubles trying to deactivate hardware flow control, and finally though it was mandatory at hardware level (RTS connected to CTS).
I've found this page about serial cabling interesting: http://www.lammertbies.nl/comm/info/RS-232_null_modem.html. They also warn null modem cable without handshaking can cause problem at software level (hardware flow control can't be disabled), so I think I still prefer having RTS connected to CTS (in this page: "Null modem with loop back handshaking"), this ensures it will works whatever the software used.
