Functions

func Dial

func Dial(addr, mycall, password string) (net.Conn, error)

func DialCMS

func DialCMS(mycall string) (net.Conn, error)

DialCMS dials a random CMS server through server.winlink.org.

The function will retry 4 times before giving up and returning an error.

func DialContext

func DialContext(ctx context.Context, addr, mycall, password string) (net.Conn, error)

func DialTimeout

func DialTimeout(addr, mycall, password string, timeout time.Duration) (net.Conn, error)

func Listen

Starts a new net.Listener listening for incoming connections.

The Listener takes care of the special Winlink telnet login.

Types

type Conn

type Conn struct {
	net.Conn
	// contains filtered or unexported fields
}

func (Conn) RemoteCall

func (conn Conn) RemoteCall() string

type Dialer

type Dialer struct{ Timeout time.Duration }

Dialer implements the transport.Dialer interface.

func (Dialer) DialURL

func (d Dialer) DialURL(url *transport.URL) (net.Conn, error)

DialURL dials telnet:// URLs

The URL parameter dial_timeout can be used to set a custom dial timeout interval. E.g. "2m".
