* ASEQNET

aseqnet is a sequencer client which sends/receives events over
network.  Suppose two hosts (hostA and hostB) connected by network.
You need to run ALSA system on both hosts.  Then, start aseqnet as a
server on hostA:

	hostA% aseqnet
	sequencer opened: 128:0

A user client 128 with port 0 was opened. (The client number may
vary.)  At next, start client on hostB.  The argument is the hostname
where server is running.

	hostB% aseqnet hostA
	sequencer opened: 132:0

Now events sent to hostA:128:0 is transferred to hostB:132:0, and vice
versa.

You can connect these ports arbitrary to other sequencer ports.
For example, connect hostB:132:0 to a MIDI output device 65:0.  The
aconnect utility can be used for this:

	hostB% aconnect 132:0 65:0

Events to hostA:128:0 will be delivered indirectly to hostB:65:0.
You'll hear MIDI sounds as following:

	hostA% pmidi -p 128:0 foo.mid

The multiple clients may exist simultaneously.  If hostC is connected
as a client to hostA, events from from hostA are sent to all connected
network clients, hostB and hostC.  However, only one connection is
allowed from a client to a server.

To disconnect network, stop all clients before server by ctrl-C or
sending signal to them.  The server will automatically quit.

The available options are:

  -p port : specify the TCP port number or TCP service name.
            Default value is 40002.
  -s addr : explicit read-subscription to the given address
            (client:addr).
  -d addr : explicit write-subscription to the given address.
  -v      : verbose mode.
