Hi,

I am trying to use netcat in linux as a tcp client to send some messages to a server.
The message is in this format

STARTDATAEND
The start of the message is a 9 signed byte and followed by 256 bytes of data and ends with a 7 signed byte  

-10%START%-10HERE_IS_SOME_DATA...................-20%END%-20

How do i send such a message containing signed byte -10 using netcat?

thanks
