Hi Grant, Take a look at this group:
RemoteKeyerInterface@groups.io | Topics
They have a simple to build keyer interface and software that will key your rig remotely. Using a Serial port (likely with a USB to RS232 adapter), you close CTS and RTS to ground to key the rig. I think DTR/DSR can be used for PTT, but I don't remember for sure. The RemoteKeyerInterface software detects the control signal changes when you kit the key and sends a "key the rig" command to the Flex over the LAN/WAN connection.
I built the interface this past summer, and it works great. I later coded my own homebrew box (TeensyMaestro) to send the keying commands, so I no longer use the RemoteKeyerInterface, but it is always in my computer bag should my own gizmo stop working.
If you want to send CW remotely using the keyboard instead of a keyer, you can open the CWX interface in SmartSDR and key directly into the CW entry window. With this approach, you won't need the RKI interface or software.
