    I a newbie writing device drivers as part of my college project.
This seems like a silly question for gurus. Help me out .

Question :
  1. What are the Hardware/Technical detail that one should be aware of
before writing a device driver ?(specifically for serial devices)
  2. Is it possible for providing virtual channel b/w two devices (like b/w
sound device and network device ) for reducing delay for data transfer . If
at all it can be done , what are possible solutions

Any help in this would be acknowledged . Please cc me your comments/answers
