Keeps telnet and ssh links from dropping
Spinner keeps telnet and ssh links from dropping due to inactivity. Many firewalls and some ISPs drop connections when they are perceived as idle. Spinner acts as a keep-alive by constantly sending a tiny amount of data over the link, preserving the connection. It displays a little "spinning" ASCII character in the top left corner of your terminal. It can also be activated with the -n switch so that, instead of displaying a spinner, it simply sends out a periodic null character to the terminal. It supports any terminal capable of handling VT100-style escape codes. It also has a mode called "Ghost in the Machine" mode, which you can use to write the spinner character to ANY tty, not just your own.
