When connecting from a device to a modem, an asynchronous cable is needed. When connecting two devices directly to each other, a "null-modem" crossover cable is needed. If you've got the wrong cable, you've got no data. Don't want to replace the cable? Cross it over with this handy adaptor.

This male-female passthrough adaptor will cross an uncrossed signal or uncross a crossed signal, thereby inverting the transmit/receive pairs on an RS232-wired 25-pin cable.
