A void device. This device will not emit any data, and will drop any data it
receives. The null backend does not take any options.

Create a two-way stream socket, which can be either a TCP or a unix socket. A
unix socket will be created if @option{path} is specified. Behaviour is
@option{telnet} specifies that traffic on the socket should interpret telnet
escape sequences.
+@option{reconnect} sets the timeout for reconnecting on non-server sockets when
+the remote end goes away. qemu will delay this many seconds and then attempt
+to reconnect. Zero disables reconnecting, and is the default.
+
TCP and unix socket options are given below:
@table @option
localhost 5555
@end table
-@item tcp:[@var{host}]:@var{port}[,@var{server}][,nowait][,nodelay]
+@item tcp:[@var{host}]:@var{port}[,@var{server}][,nowait][,nodelay][,reconnect=@var{seconds}]
The TCP Net Console has two modes of operation. It can send the serial
I/O to a location or wait for a connection from a location. By default
the TCP Net Console is sent to @var{host} at the @var{port}. If you use
the @var{server} option QEMU will wait for a client socket application
to connect to the port before continuing, unless the @code{nowait}
option was specified. The @code{nodelay} option disables the Nagle buffering
-algorithm. If @var{host} is omitted, 0.0.0.0 is assumed. Only
+algorithm. The @code{reconnect} option only applies if @var{noserver} is
+set, if the connection goes down it will attempt to reconnect at the
+given interval. If @var{host} is omitted, 0.0.0.0 is assumed. Only
one TCP connection at a time is accepted. You can use @code{telnet} to
connect to the corresponding character device.
@table @code
sequence. Typically in unix telnet you do it with Control-] and then
type "send break" followed by pressing the enter key.
-@item unix:@var{path}[,server][,nowait]
+@item unix:@var{path}[,server][,nowait][,reconnect=@var{seconds}]
A unix domain socket is used instead of a tcp socket. The option works the
same as if you had specified @code{-serial tcp} except the unix domain socket
@var{path} is used for connections.
