Oh, wow, it's going to be a learning experience!

I've pretty much decided to load the VNC1L on my board and essentially build a VDIP1 on my host board. As I mentioned this is for a keyboard input and I'm concerned about lack of handshaking. Not knowing exactly how the VNC1L acts, I'm rather expecting it to just dump the keyboard characters out it's TXD line when I'm not looking for them.

I see the brick wall coming, and am going to have to implement some kind of handshaking to control character flow. Any ideas? Thanks for pointing me in the right direction!
