========================

A serial to telnet client and library as replacement for ser2net.

# How to use the library

To spawn a telnet server on port 5555 and redirect to ttyS0 running at 115200N8 use this code

example:

```

import (

	"github.com/9elements/go-ser2net/pkg/ser2net"

)

        w, _ := ser2net.NewSerialWorker("/dev/ttyS0")

	// Run serial worker in new routine

        go w.Worker()

	// Start telnet on port 5555 and serve forever

        err := w.StartTelnet("", 5555)

        if nil != err {

                panic(err)

        }

	// Start GoTTY on port 5556 and serve forever

	err = w.StartGoTTY("", 5556, "")

        if nil != err {

                panic(err)

        }

```

To use an io.ReadWriter do:

```

import (

        "github.com/9elements/go-ser2net/pkg/ser2net"

)

	w, _ := ser2net.NewSerialWorker("/dev/ttyS0")

	// Run serial worker in new routine

	go w.Worker()

	// Get a ReadWriteCloser interface

	i, err := w.NewIoReadWriteCloser()

	if nil != err {

		panic(err)

	}

	defer i.Close()

	// Copy serial out to stdout

	go func() {

		p := make([]byte, 1)

		for {

			n, err := i.Read(p)

			if err != nil {

				break

			}

			fmt.Printf("%s", string(p[:n]))

		}

	}()

	// Copy stdin to serial

	reader := bufio.NewReader(os.Stdin)

	p := make([]byte, 1)

	for {

		_, err := reader.Read(p)

		if err != nil {

			break

		}

		_, err = i.Write(p)

		if err != nil {

			break

		}

	}

```
