Eicon Diva ISDN USB

Hi there,

I have an Eicon Diva USB ISDN adapter which works perfectly with W2K/XP.
Checked on their website but there is no drivers/support for any other POSIX
brand OS.
I would like to try and write a device driver for QNX. Could you give me
hint regarding the QNX specific libraries/function calls i should pay
attention to?
Or maybe there is already a similar project to which I can join?

Thanx,
Mitko
