Serial comunication with screen
If you would like to build it manually first you need to build ncurses and then build screen. Easiest solution would be try to use buildroot (http://buildroot.uclibc.org) where package screen is included and you can simply select it by kernel style menuconfig.
Probably the easiest way would be to install debian om emdebian on a sd card and install screen just with "apt-get install screen". But if you need the default qtopia then that is maybe not the best option..
