serial on lombard

Hi there,

there's something I cannot get rid of. When I try to
use minicom to dial with the internal modem of my
lombard 400MHz I get a "/dev/ttyS0 no such file or dir"
error; when I try to use setserial or stty on the same
device everything works ok. I'm using debian potato.
Attached there 's the 'strace minicom' output: hope this helps.

Thanks guys and ... great work !
