// Companion code for the Linux terminals blog series: https://dev.to/napicella/linux-terminals-tty-pty-and-shell-192e
// I have simplified the code to highlight the interesting bits for the purpose of the blog post:
// - windows resizing is not addressed
// - client does not catch signals (CTRL + C, etc.) to gracefully close the tcp connection
// 
// Build: go build -o remote main.go
// In one terminal run: ./remote -server
// In another terminal run: ./remote 
// 
// Run on multiple machines:
