How to access the modem in QtMoko

[robin]

how do I communicate directly with the modem on /dev/ttySAC0?

Is there some easy eg python wrapper to communicate with the modem as eg in
shr?

For the direct acces I tried  cu -l /dev/ttySAC0 as it is stated on the 
openmoko wiki site but I get 'cu command not found'. does anyone know which
package I have to install and if it is still necessary to do
chown uucp.uucp /dev/ttySAC0 to be able to access the modem?

thank for your help
