This program is sample code to send some messages via TCP. It is written with Rust.
tcpclnt-rs reads messages from std I/O, then you can use redirection like;
tcpclnt-rs < hoge.txt
tcpclnt-rs can understand one argument, connection IP address and port number.
tcpclnt-rs 127.0.0.1:1000
If there is no argument, it will connect to 127.0.0.1:1000. Or you can customize to any.
It is for a programable device using TCP.
