Writing from an editor Gadget

Hi,
I'm still pretty much a beginner. I'm putting together a small app to read and write to a serial port. I can read from a string gadget and send that to the serial port ok, and I can write incoming text to the editor gadget.

However, if I want to write character by character as I type from the editor gadget to the serial port it does not seem at all straightforward.
This is for windows so should be I be looking at the API for keyboard or the editor controls?
If someone could just point me in the right direction as looking through the forum there seems to be a number of possibilities but I'm not sure which way to go.

Thanks

Mmmm. From the editor gadget would indeed be a bit tricky... Either you would have to compare new and old contents of the gadget, and send the differences (not good) or grab and process keyboard input before passing it on.

What are you trying to build? A terminal app or something similar?

A terminal yes.
I can do what I want to already (talk to a PIC controller) using string gagets etc. but I thought it would be good to move it on a little, but I think I might be going a step too far for what I know.

Thanks for your survival guide BTW, it has been really useful
