How to use Uart module with a serial mouse?

Hi,
When I start
devi-hirun -l
It give me a list of available modules:
Uart,
Fd,

But when I do
devi-hirun -vvvvvv msoft uart
After giving the messages of initialisation (which seem correct), it hangs
and the mouse does not move.
Any insight?


Any help would be appreciated.
