Alternately, every module may be given a unique remport number, requiring that a host program bind a unique UDP socket to each of these unique remport numbers. Then, when a particular socket receives a UDP datagram to its unique port, the module sending it is automatically identified.

The optional ipaddr parameter is normally unspecified, causing it to default to use the IP address of the current TCP/IP connection. That way the host need not have to be aware of its own IP address. This parameter is provided in case a special host has multiple network interfaces and wants to use more than one. When used, ipaddr requires four dotted numeric fields (d.d.d.d). Each d is a 1-3 digit decimal number in the range 0-255. The ipaddr = 255.255.255.255 is best avoided, unless the UDP datagrams of streams are to be broadcast to all network nodes.

The ‘f’ parameter identifies the format of each selected acquired datum in each stream packet, and is a single numeric digit. Valid format codes are listed in the following table:

Example:

Configure all streams to be delivered via UDP/IP protocol. Host expects the UDP datagrams to arrive via port 7500. The IP Address of the current TCP/IP connection is also used to send each UDP datagram.

"c 06 0 1 7500" Read response:

"A"

Configure all streams to be delivered via the default TCP/IP protocol.

"c 06 0 0"

Read response:

"A"
