I am using a CP2108 in my application, but I've chosen not to implement handshaking. What should I do with the unused handshake pins (RI/DCD/DSR/CTS/RTS/DTR)?
If you are certain you'll not need to support any handshaking, you can manage these unused pins in your system by:
* Do not use Flow Control
* Leave the handshake lines FLOATING
This should provide a robust system configuration for the CP2108 when handshaking capability is not used.
