This DataPro 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.
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 have the wrong cable, cross it over with this coupler.
