It's the "&" that's giving you the error message.

Programs like "top" accept keyboard input (i.e. "q" quits).
It cannot run in the background, even on the local tty.

You might want to try it without the "&", or maybe redirect
the input from the serial port too.  
i.e.  "top > /dev/cua0 < /dev/cua0"

If it still gives you trouble, you might have to set the
terminal type and/or stty settings.  Try something like:

(
stty ...
export TERM=vt100
top
) > /dev/cua0 < /dev/cua0

-- Or -- you could try running it in one xterm, and 
"tee" the output to /dev/cua0 also.

Good luck.  Let me know how you make out.
