It must depend on VMIN and VTIME. I didn't mean you were wrong. The action of "no data" can vary, depending the combination of VMIN and VTIME. I was clarifying what I wanted. > But whatever.

I never considered altering VMIN in flight. My application proxies sockets to serial ports in a select() loop, and I want to keep it simple. But thanks for the idea, I will ponder it. > Enough wanking. Time to get back to solving *real* problems. It's not hypothetical to me.
