I believe crossed wiring is not the same as null. The term crossed comes from the appearance of a ribbon cable at the solder-side of a DB9 plug: the ribbon cable has every other wire going to the bottom row of DB9 pins and the remaining going to the top row of pins. I may have muddied the waters by using the term crossover instead of crossed. If a MB connector designed for a straight through cable is connected to a DB9 using a crossed cable, the pins will have the wrong signals, i.e.: expected will be DCD will be DCD RX will be TX TX will be GND DTR will be RTS GND will be RING DSR will be RX RTS will be DTR CTS wiil be DSR RING will be CTS I would be surprised if a null anything could straighten this out. -Denis _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
