A uart driver to control modem

Hi everybody,

I'm a newbe on linux emb development.
In a mpc880 based board (kernel 2.6.19) I've to control a modem
using a scc with handshake signals on general I/O ports.
Reading code of cpm_uart driver, it seems don't manage
handshake signals whereas uart driver (<2.6.10) seems do this.
It's correct?
Could you suggest the right way to start?

Thank you,
Andrea
