TCP/IP Large Data Communication

Hi,

I try to write approxiametly 1 MB data over ethernet. But MATLAB send data as 1408 byte as only one packet and remaining bytes not send exactly. There is a communication issue. When I use a TCP/IP terminal such as Realterm there is no problem to write data exactly. I work on an embedded system which takes packets each of them is 1460 bytes and merge them to use on application. How can I write this 1 MB data correctly on Matlab. Can you help me?

Thanks in advance.
