I am trying to get a console connection to a gpsstix. I have a 3/5V TTL to RS232 converter with the pins connected as follows:

Computer                 Converter (RS232)            Converter (TTL)            gpsstix FFUART
    Rx ------------------------------ Rx                               Rx -------------------------------- Tx
    Tx ------------------------------ Tx                                Tx --------------------------------- Rx
    GND -------------------------- GND                             GND ----------------------------- GND
                                        Vcc                              Vcc ------------------------------- Vcc

Do I need to connect the CTS, RTS, DTR, DSR, CD on the computer to anything?

These are not available on the gpsstix because they are used for the USB client.

Should they be configured for loopback handshaking?
