Line idle is signal high --> -12V nominal A byte frame starts with bit wide elements: a startbit : low ( -12V nominal) n databits : H or L if parity : H or L depends on parity sense and the data value) Stopbit : 1 or 2 cells high If the line stays low longer than 1 + n +(p?) cells a break is generated the same happened if the currentloop in rs422 was broken ( thus the name ) The linux tty driver (can/will) return \0 for parity and framing errors or break. You get forex a break when the sending baudrate is a lot slower than the receiving rate.
