I've made a small servo pan/tilt mount that I'd like to be able to control from the keyboard of my computer, but currently the only way I can find to do it is by typing in letters into the serial window and hitting enter. Is there a way to have it such that when you type a letter it's automatically sent, so that it'd eliminate the jerkiness?
Alternatively, does someone know how to just control such a mount using the keyboard arrow keys? I've seen videos of a setup like that but I haven't found any way to do that.

You don't say what you're using, but a proper serial terminal emulator (like the old Windoze Hyperterm) would let you do what you want.
That gets rid of the having to press enter. Thanks! It's still a bit jerky, though, due to the keyboard only reading the letters at a certain speed. Do you know of any way to get the arrow key control to work?
You will probably need to write/develop a program to run on your pc to monitor for the arrow key press, then send the desired data to the com port. You should be able to use any number of programming languages to do this. You may want to look at "autoit" or something similar for a quick solution. The "jerky" issue may be something beyond the keyboard control.
use processing or a vb app.
