Okay, this is where things get cool. For you folks who have issues with
The teletype is connected to one of the original 300 baud Hayes Smartmodems
I had in a box doing nothing which solves a lot of problems with trying to
make an older dataset work with the much more plentiful Smartmodems and
their later clones by just about everyone. (which as a few have mentioned
have no issue working at 110 but with a catch) That I've found so far you
can dial pretty much any other hardware modem that isn't relying on a DSP or
sound CODEC (so late ISA and all PCI cards don't work) and it will work by
pure modulation. You just need to make sure the COM port on the machine is
set for (or will automatically detect and switch to) 110 or else it assumes
300 and nothing works.
The quirk I added however is that I took the guts of the teletype's UCC6 and
a TWX controller and built a custom CCU that gives me feedback on the modem
status and lets me control and dial from the front panel. The modem itself
now hides in the stand and I don't need to type in commands to do anything.
It looks as if it's a factory option. I even added a feature where in
Automatic Answer mode the motor is relay controlled by the modem itself.
I have a massive writeup and a video that are about ready to go live but I
need a set of videos demonstrating the setup connecting to a remote user,
connecting to a remote machine and a remote user dialing into the teletype.
That's where I was having my troubles.

People have been nagging me for the last year to get a Panasonic 308. I've
yet to come across one so far that wasn't weirdly priced, plus my parents
aren't interested in a PBX being installed in their house.
