Ok. I shot the mouth off too soon. Restructuring all of the parenthesis so they lined up cleared up a couple of issues. People who use that type of indentation and bracket-matching obviously don't do hand traces all that often :\ (Thats a joke, so please, no flames). Anyhow, I've reduced myself to one question. Or, more acurately, one point that I need clarification on. I see now that PPPD leaves the port in a non-blocked state for the duration of the call. I guess I don't see why... After all, it could be left blocking, and I/O could be first checked for with a select call. I guess the question I really have is this... With the other serial drivers, what keeps pppd from spinning completely out of control (if its not selecting/ blocking on the async port)? -Brian
