UDP is as his name say a datagram protocol. There is nothing in UDP itself
which relate one packet to another. You have to design that at the
application level if you need it. TWSocket does nothing with your data, just
pass it along.
The largest packet you can send with UDP is governed in ICS by the BufSize
property. You may enlarge it if it is needed by your application. Note that
all transport layers may not be able to transmit large packet, specially
over internet.
Also, don't forget UDP is by design an unreliable protocol. This is how
TCP/IP has been designed and is not related to ICS capabilities. See
"TCP/UDP primer" document available at my website on the support page and
also in the wiki.

Subject: [twsocket] Concatenate multiple UDP packets
Hello,
I am using a combination of the SendStr & ReceiveStr functions to send
commands to a remote server and display the responses from the server in a
RichEdit control and everything seems to work fine as long as the
information that is received comes back in one packet however if the
information comes back in multiple packets only the first packet in the
series is displayed in the RichEdit control so I was wondering how I might
concatenate the packets that are received so they are all shown at the
same time. The packets are sent/received via UDP if that matters and
wireshark reveals that each packet in the series is terminated with the 0A
(or #10) character but there doesn't seem to be any way to tell the
difference between the first packet in the series and the last packet
because they all end with 0A so how could this be done.
Thanks,
Dave
