Description=Fly Mail is a tiny program that lets LAN users send instant messages through TCP/IP. It's free but quite robust. It runs in the background, requires no installation, and offers a choice of an English or Russian interface. Features are limited, but you can print and scroll through sent as well as received messages. You can even choose to attach a file and send it along with your message; but beware that there's no warning if you're going to overwrite another file with the attachment. Navigation is straightforward, so the lack of documentation shouldn't be a problem. With Fly Mail running, simply click on Send New Message to choose someone on the network and type a quick note. Optional audio alerts can signal that a new message has arrived. Options for Fly Mail to pop up when messages arrive and to run at startup can be easily toggled on and off through the menu. However, any changes to the TCP port have to be done manually in the INI file.
