[GreenKeys] Computer to teletype module...

[keelan at beefchicken.com]

If you have an existing TU, and appetite for the ridiculous, I have been recently developing a 'backwards modem' that uses your computer's sound I/O to talk to a TU, which is then connected to a teletype. The current incarnation supports a Hayes Modem AT command syntax, and using it you can use a Teletype to establish TCP connections to the internet. The modem is "backwards" because the DTE interface is the modulated interface, whereas in a normal modem, the DCE interface is the one that is modulated.

The Modem and RTTY DSP library is written in Google's Go programming language, which is cross-platform. I do all my development work on a mac, so I know it definitely works on macs! The goal of my project is to install the software on a Raspberry Pi, so the Pi can act as a stand alone AFSK<->Internet gateway. The whole iTelex thing is neat, but I can't be bothered with constructing the plethora of over-complicated hardware (apologies to those involved) needed to make it work.

If this is something you'll have the patience to mess around with, I'll expedite getting my code up on GitHub.
