problem using two serial devices at the same time

I'm using the TWR-K60F120M with the TWR-SER board using both available serial ports at the same time.  I have the shell running on the OSJTAG port without problem (ttyf) now I'm trying to use the serial port (ttyd) for a custom protocol, but for now, I'm just opening and writing a test string to the port.   The open and write are not returning any errors, but the test strings are not what I'm reading from the TWR-SER connector.  Instead, I'm seeing a duplicate of all the shell output from ttyf.

 

Any thoughts would be appreciated.  I don't understand why I'm seeing this.
