[GreenKeys] USB TTY (Was Do you know this person?)

 Bill,
  Yes I would be interested.Has anyone ever attempted RTTY over VOIP?Just wondering if any of the VOIP codecs have good enough fidelity totransmit FSK.Maybe that is overkill. Why modulate baudot to send it over a digital medium..-Steve

  I have a couple of projects that do the Baudot-ASCII & baud rate conversion. One is an Arduino project
that I built to make my M33 (ASCII, 110baud) communicate with Baudot devices (45,50,75 baud). It would
work fine making a M15,19,28, etc. talk with a computer. The other is a PC application that connects to
COM ports which can be either 5 bit Baudot or 8 bit ASCII, primarily used to connect my M28 to a Baudot
TU, but any combination can be used, as well as communicating to/from the PC.

In the back of my mind I have had an idea to create some sort of application that would allow the old
teletypes to communicate over the internet, somewhat akin to iTelex, but not requiring a specialized
boardset. A PC or Arduino or Raspberry PI would do the job just fine. My PC application would not
take a whole lot more work to make that happen.

If I knew someone else would use this application, maybe I could get inspired to make it happen.

Anyone?

 Steve,
I try to only tackle one problem at a time to avoid getting overwhelmed, and right now that's still locating a couple of working teletype machines or machines that could be made to work — one for Newton, Mass. and one for Seattle.
But last night I was watching the channel of the YouTuber called CuriousMarc and wondered if he's published schematics or instructions anywhere. I'm sure you've seen his videos. You can see the hardware he's used to connect his teletypes to a Linux PC. I'm not an engineer, but I'm capable of following plans, wiring and soldering, and persistent. Were I able to build one, I could build three.
This is one of the many times when I wish my Dad were still alive. He was a brilliant MIT-trained electrical engineer and excelled at crushing these sorts of hacks. He died of cancer in 2018.

 Chuck,
  Have you had any luck finding plans for an interface between the Mac and the TTY?I might want to take that route at some point so I am curious what you come up with.Someone on here posted a wiring diagram showing how to use a polar relay to connect toRS232 but I don't know how you would deal with the baud rate and ascii to baudot conversion.

 Steve, an expert behind a screwdriver sounds great to me. The further along a machine is toward tuned, probably the better chance I have of success (and staying on this list!).
Also thanks to James and everyone else who's offered assistance. No reply yet from the Craigslist ad for the UPI RO in Metuchen, NJ.

Before, I mentioned my impetus is that I have a kind of writing partnership with another writer in Seattle. (I work for a TV network, but he's an actual professional writer, for places like Disney and Pixar.) We work on episodic scripts together either in cloud apps or sending them back and forth by email (so far unsuccessfully, but in scriptworld things can change quickly). This has been complicated recently because he's discovered his grandfather's typewriter, loves it, and believes its more cumbersome nature slows him down, to his work's benefit. He believes the moments of extra time he spends waiting or pressing keys, he also spends thinking, and it's actually improved his writing. (It might be true.) He's been encouraging me to try this, but I'm not ready to give up screens and software, and when I told him instead of getting a typewriter, I was going to try to set up a teletype to type out my scripts, he was like, what's a teletype? 
Originally I thought I'd output from the Mac laptop to the teletype and mail him the pages or roll. But then I thought, what if we each had a teletype, and I transmitted the script over the net to it instead? I could call him and tell him to turn the machine on, and it'd type the script out at his house instead. He could watch it come through a character at a time if he liked. And when he finished one, vice versa.

 Chuck,
  I am holding on to your contact information because I have an Associated Press M15 ROI might let go after I get it working.I have since acquired a M19 so I do not need both.I will keep you in mind. I paid $50 for it and bought parts. I would rather sell it as a working unitrather than a basket case. Stay tuned.

 Hello GreenKeys,
Is the person who posted this UPI machine on Craigslist on this list? Or does anyone on this list know this person?
https://cnj.craigslist.org/zip/d/metuchen-vintage-upi-teletype-machine/7349823306.html

I've sent a couple of emails, but so far, crickets. If you're them, please call me, or if you do, please let me know or just give them my number. I haven't found a teletype yet and I'm really champing at the bit to get started.
Thanks,Chuck RobertsonNewton, Mass.(206) 579-0321______________________________________________________________
