Need example of sending TCP packets to a listener

[Erik-k]

Hello, I want to send data (probably in the form of TCP packets) to another device on a WAN which is listening with $netcat -l . I can't understand the SyncClient example well enough to figure this out.

Sorry for begging but will you please give an example of how to craft a TCP packet and send it to another IP:port address?

Will you connect to that host every time you want to send a packet or will you stay connected to it?

[Erik-k]

I'll stay connected to it.
