Sure, if you don't need "input" (only "console logger" function and not "initial input/output terminal"). It has nothing to do with the RTS "problem", though. BTW: reasonably working, standard-compliant USB-RS232 converters cost $15 or so. Unfortunately not that all machines have USB ports. I agree with Russell - mixing kernel console and application's port is asking for trouble. OTOH I wonder what does the device in question require WRT the serial port and WRT RTS line in particular. I know there are some half-duplex converters which drive RTS only while sending and which require CTS to send. They are perhaps a bit broken and require some CSMA-alike retransmissions etc. I don't know if one can expect RTS to stay low all the time. Even a simple /sbin/setserial from /etc/rc.* would drive it high for a moment. I'm afraid the only way which makes sense may be using a customized plug. -- 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/
