mini2440 - accessing function keys for terminal app

Casey Dillard
Hello everyone, I'm new here.
I'm using a new mini2440 w/ the linux/qtopia that was pre-loaded with it.
My purpose for it was to monitor and display serial data from the serial
port on a large lithium battery. I was able to compile picocom to open a
connection to the battery. My problem is that I need access to F1 & F4 keys
to navigate the interface and there are no F-keys on the built-in stock
keyboard. Is there any simple way to re-map those keys to another built-in
key on the keyboard so that I'm not having to use an external keyboard?
I'm not a linux expert but I know how to run command line apps and I can
compile simple C programs(I compiled picocom to the mini2440).

Any help would really be appreciated!

Thanks!

Casey
