- The problem is - what do you understand so far about how CWType works?
Do you understand that you are asking how to build or find a piece of hardware - not software. CWType is the software and uses a hardware interface to key the rig.

You will see very simple circuit with 5 parts you can find cheap at R. Shack. I build mine inside the Serial plug itself.
The link also shows a picture of of a finished product.
Here is a link where you can buy it - or could buy it (haven't check if it is still available): http://www.hosenose.com/store/productgrid.aspx?primarycatid=47
Over the years CWType has evolved and as I use the original basic "hardware" interface, I haven't bothered to keep up with CWType's evolution to interfacing with winkey etc.
I just know the above works and can be made for probably under $10 in parts. Or you can buy a ready made version at the link above for $25.
In short - CWType sends a "pulse" out the computer serial port. Somewhere between that port and your rig, you have circuit that using a switching transistor to turn that pulse into what looks like a straight key on/off to the rig. The circuit needs about five parts- two resistor, two diodes and a transistor. It is just as if you had a cable with the appropriate plug for a straight key if you were using a straight key with your rig - the rigs I've had use a 1/8 stereo plug with the ring not used and a menu setting that tells the rig to "look" for a straight key instead of a paddle.
If you are asking how to use CWType to send modulated CW to the rig - maybe it does that now, maybe not. The above is how it originally worked and still does - very well.
It dovetails nicely with the companion CWGet, though its a whole other forum to discuss the merits of Rig CW to computer soundcard to software app CW translation.
