Is your UPS using "modern" hardware handshaking (CTS = PC can send, with RTS practically always asserted)? Or perhaps the "old", "half-duplex" V.24-style (RTS asserted before TX and then waiting for CTS)? Are you sure it uses hw handshaking at all? Most (all?) UPSes I used had only TxD and RxD (for RS-232). -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
