My apologies,
My one device has tx, rx and ground screw terminals. The other device is a rs232 connector.
*facepalm*
Again, there is no such thing as an 'RS232 connector'. I'm going to take a guess here and assume you mean a DB9 connector - although I can't be sure.
In such a case, you can just cut the end off a DB9 cable. You will need to know the PIN out for the cable and then use you meter to check which wires go to the pins you need.
Or you could order a cable with bare wire on one end already and labeled:
