You just need a simple gender changer, and  as someone suggested, *not* 
a null modem type, which switches a pair of wires.

Of course, you need to have the  correct comm port selected in the 
software.   You may have to go into device manager to confirm what comm 
port the usb thing installed as.    Also be sure baud rates match in 
both software and radio.  If you change baud rate in the radio, you need 
to  power it off and on again for the change to take effect.
