NEWBEE "reverse ioctl" or someting like

[sébastien person <sebastien.person@xxxxxxxxxxx>]

hi,

I've made a network driver wich is attached to the serial port.
The network hardware is able to return information to the pc. theses
informations are belong to the configuration of the hardware. I 
succeed on receive information in the driver but I've no idea to alert
higher process (like configuration app ...) that I've received something
(wich is not network data like TCP or ARP etc ...).

I think that use of pipe isn't preconised because I must fork process
to use pipe, I search something like ioctl but in the other way : 

 kernel process ---> user process

Is somebody know the best and easy way ??

thank (I hope this is the right place to ask)
