If I am reading the code correctly, it does not need anything other than Tx/Rx/Ground (ser_open() sets CLOCAL, which ignores modem control lines). So that cable should work. > or > http://web.archive.org/web/20100106160328/http://ups.miem.edu.ru/ups_faq5.html > (cable 5.4.1)? The loopback connections would be for the modem control lines (hardware handshaking, which your UPS probably does not do). Other than that, I think the DB-9 pinout is the same. nutdrv_qx would be best, but blazer_ser is the next newest driver. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
