Your best bet is really to look at the existing drivers; if you're doing serial comms stuff the 'sio' driver is _the_ place to start. Then start asking questions here; there are plenty of people that can help you out. A while back Eric H. was working on a driver writer's guide, but it's very hard to know where to draw the line between "this is a BSD-specific issue" and "this is something about device drivers in general". The 4.4 Daemon book is also a useful reference, although a bit distant from the current FreeBSD implementation. > We've developed a number of high performance communications boards > for FreeBSD.
