func Open ¶

func Open(path string, mode *serial.Mode) (serial.Port, error)

Open configures a serial port and gives its writes to Go's poller. The serial library already provides interruptible reads, but its Unix Write uses a blocking syscall that closing another goroutine's descriptor need not stop. A separate nonblocking descriptor makes pending writes interruptible by Close. It is opened before terminal exclusivity is claimed; both descriptors share the same terminal configuration.
