Let me just throw out one caveat here: Many UPSes that use a serial port don't really utilize it to transfer serial data, but rather just raise/lower some of the signal lines to let the software on the host know something has changed. Of course, lots of them, especially newer/smarter ones DO pass serial data. But if this one is one of the dumb ones, the cable may not even be a normal rs-232 cable, so trying to monitor it with a terminal may not produce much useful information. > > Anne > _______________________________________________ > CentOS mailing list > CentOS@xxxxxxxxxx > http://lists.centos.org/mailman/listinfo/centos -- ---- Fred Smith -- fredex@xxxxxxxxxxxxxxxxxxxxxx ----------------------------- The eyes of the Lord are everywhere, keeping watch on the wicked and the good. ----------------------------- Proverbs 15:3 (niv) -----------------------------
