I briefly mentioned in #cemetech about a week ago a project I'm working on called "tinc", short for "TI netcat". My original plan was to write a program that can talk to a calculator and can either connect or listen for connections over the network. The current incarnation doesn't speak over the network but rather only over stdin/stdout, but it can still speak over the network with the help of nc (or perhaps even inetd). If I decide not to add networking functionality to tinc, I'll probably rename the project to "ticat".
I've been working with Lionel Debroux and Benjamin Moody to make it work with ticables reliably. Now it's at a point where it should be pretty stable (but it's still not ready for a real release yet). I've only tested it with TiEmu and Punix (not that the OS should make a difference).
Get tinc here: https://github.com/abbrev/tinc
Anyway, here's a little networked tinc demo (using nc for the network part):
Code:
In Punix on the calculator (TiEmu) I ran the "uterm" program, which is a terminal program that talks over the link port (kind of like minicom in *nix or Hyperterminal in Windows). Then I browsed to http://localhost:8002/ in Firefox.
In the following screenshot, the first 9 lines (11 lines with line wrapping) starting at "GET / HTTP/1.1" are the HTTP request from Firefox. The next 6 lines (starting at "HTTP/1.1 200") are the HTTP reply that I manually typed on the calculator. Firefox displayed the text "Hello world!" in plain text as soon as I hit enter on the last line. Hooray for an impractical web server.
Another use for tinc is to use the Punix shell from a real terminal. This works only if Punix is listening for logins over the link port, which is not the case with the demo above (the link port can be opened only once at a time in Punix).
Anyway, here's a short run using the Punix shell in my Linux terminal:
Code:
This was actually my first use of tinc, but I think the HTTP demo is more impressive.
I hope I can get tinc ready for release before too long, and I hope we all can find useful and innovative uses for tinc. I already thought about writing a VNC server for Punix as a sort of replacement for the TI screenshot functionality. Who knows what else we can come up with?
Edit to mention Benjamin Moody for help with ticables.
