serial: A Go repository from adenis78

invented the bicycle)) Simple fork of goburrow/serial to use setterm() from termios lib AND use non-standart (non-posix) termios.Cflag 0x40000000, to manipulate 9 bit's MARK and SPACE states. Changes (after original goburrow/serial):

serial_posix.go: newTermios(&config) => NewTermios(&config) (now it is public)
serial.go: add SetTermios(termios) to Port interface (not need to reopen port to apply new termios settings)
serial_posix.go: add 0x40000000 bit ops, non-posix. tested linux only (new debian 9.8 and ti arm embed with old kernel 2.6.x)

Example

package main

import (
	"log"

	"github.com/adenis78/serial"
)

func main() {
	port, err := serial.Open(&serial.Config{Address: "/dev/ttyUSB0"})
	if err != nil {
		log.Fatal(err)
	}
	defer port.Close()

	_, err = port.Write([]byte("serial"))
	if err != nil {
		log.Fatal(err)
	}
	
	config.Parity = "M"
	config.StopBits = 1
	
	termios, _ := serial.NewTermios(&config)
	err = port.SetTermios(termios)
	if err != nil {
		log.Fatal(err)
	}
	
	config.Parity = "S"

	termios, _ := serial.NewTermios(&config)
	err = port.SetTermios(termios)
	if err != nil {
		log.Fatal(err)
	}
}
