Are you reading it back from the same port you wrote it to? What does that have to do with the cable? You can set a serial port to echo the input, but it just seems odd.
One other thing: if you connect 2 serial ports, and write to one at one speed and read from the other at a different speed, you will get either _Nothing_ or garbage. You can see or set the speed with stty -F <device> but the app can and probably will change it when it opens the port.
