Hello. Problem I found Is that it's impossible to make 2 scripts communicate eachother using TCP, isn't it? Minimum I found possible is using 2 diferent ports and 4 diferent exes and open ports on both side. 2 that recv and 2 that send packets. I wonder if it's possible to make 2 computers communicate eachother by using only 2 exes - 1 in computer A and other in computer B. I want also use only 1 port. I also want that only server side would require open ports. But I have no idea how to code i
