Yes, with another MAX232, or bypass the MAX232 somehow.

Tnx, should lines be exchanged on another max232? rx,tx->tx,rx – Mar 18 '15 at 12:00
Of course. Otherwise you'll be transmitting to a transmit pin, not a receive pin. – Majenko Mar 18 '15 at 12:07
Thank you for confirmation, something else doesn't work :) – Mar 18 '15 at 12:08
