Thank you very much for your detailed and complete answer. I forgot an important detail: the system is dual boot, Windows XP and Mandriva 2010.0. Using Windows on the same pc CNC and software works. So probably RS232 hardware works. Anyway I'll try to get a null modem or a datascope to check. Waiting for signal check is there any setting I need to have RS232 working ? Or a software check for RS232 in Wine? Is there anything like a terminal in Wine ? Till now I just installed Wine and then the software.
