SET IP

IP Item
NEW	SET	ATTRIBUTES	MESSAGES	PROTOCOLS

The shell ip item implements the following commands:

CLOSE

SET ip CLOSE

Close open connections. Connections can be reconnected using the CONNECT command.

CONNECT

SET ip CONNECT [ raddr rport ] [ /u ]

Open a connection to a remote server. If the connection is accepted, the CONNECTED message is sent to the shell.

ip

The name of the ip item instance.

raddr

The remote ip address to connect to. If raddr is not specified, the raddr specified by the last CONNECT command is used.

rport

The remote port to connect to. If rport is not specified, the rport specified by the last CONNECT command is used.

/u

If specified, the UDP protocol is used for the connection. Otherwise the TCP protocol is used.

Example:

#raddr := set '192.168.1.25'#rport := '7000'#ip := new ip *$#ip connect $#raddr $#rport /u

LISTEN

SET ip LISTEN laddr lport [ /u ]

ip

The name of the ip item instance.

laddr

The local ip address to listen for connections on. If an asterisk is specified, the ip item listens on all local network interfaces.

lport

The local port to listen for connections on.

/u

If specified, the UDP protocol is used for the connection. Otherwise the TCP protocol is used.

RECEIVE

SET ip RECEIVE [ table|variable [ field ] ] // client

SET ip RECEIVE socketId [ table|variable [ field ] ] // server

The ip item's RECEIVE command retrieves the next message from the queue of received messages. If successful, the local variable #ipreceive retrieved data.

ip

The name of an ip item instance.

socketId

The id of the socket to retrieve the message from. This parameter must be specified if the ip instance is acting as a server.

table

A table item to store the received data in. This should be a simple table for a string message and an parameter table for a numeric data message. Note that this parameter is optional. If you do not specify a table, a table of the correct type is created for you. If the command is successful, the local variable #ipreceive contains the name of the table item containing the received data.

variable

The name of a variable to store the table name in.

field

If a table parameter table is specified, then the first field to retrieve data into may also be specified. If no field is specified, the first field is used.

RESET

SET ip RESET

Close open connections. Connections can be reconnected using the CONNECT command.

SEND

SET ip SEND [ socketId ] table|string [ /p ] [ /m ] [ /u ]

The SEND command sends data to a remote host using an existing connection.

socketId

If this ip instance is acting as a server, then a socket id must be specified on which to send the data.

table

A table item containing the data to send. The type of data you can send depends on the protocol.

string

/p=o|s|a|u

Specify the data protocol. The following protocols are supported:

o - Open Sound Control (OSC) protocol

s - STx protocol

a - ASCII text

u - Unicode text

If no protocol is specified, the STx protocol is used by default.

/m

If specified, a SENT message is sent when sending is completed. This is not the same as the READYTOSEND message.

/u

If specified, strings are sent as Unicode. Otherwise they are sent as ASCII.

Example:

#ip := new ip *$#ip connect localhost 5000// send 'hello' as ASCII text$#ip send 'hello' /p=a
