How long a message can be sent via TCP using the TCP Read VI?

[Marinica]

Hello,
How long can be a message sent between a TCP server and a TCP client using the TCP Read VI (LV2013)? There is a certain limit?

Thank you.

How long means, do you mean the length of the message?

I think it just depends on your hardware's buffer size.  TCP sets limits on the size of packets that can be seent.  What are you trying to do?

Yes, how much data are you wanting to send in one message? TCP/IP doesn't have any inherent limits since it automatically breaks up long messages into shorter packets that are reassembled at the receiver.

Thank you for the information.

I have to send an array of clasters. Let say 200 elements, each element contains one I32, one DBL and a string with an avarge leght of 16 ASCII characters. All these flated to string can be around 5000bytes. As you mantion isn't my concern about fragmentation, the TCP protocol will make this for me.

On the other hand, the TCP Read VI has a mode option (Standrd, Baffered, CRLF and Immediate). If I use Immediate mode with 10000 charcaters (more then I expected), will reteurn it the 5000 charcters in one block? But I can check my self this isue...

Thank you again.
