[GreenKeys] Loop over IP

[Jeff G]

Thought this might be an interesting discussion and was a leftover thought
from Saturday...has anyone established a "loop over IP"? What I mean is the
ability to DIRECTLY convert a current loop to something like a wifi or
ethernet interface, then convert it back on the other end. Technically this
would be like what iTelex does, but includes call handling/connection
capability into the mix.

I use the word directly because I'm thinking it would be a raw
hardware-layer binary stream; not ASCII, not Baudot, but raw "whatever is
on the loop is what gets sent", so it could potentially be used for any
protocol, like morse code even.

I suppose the easiest/closest thing to slap together would be a RTTY stream
ala ITTY, as really thats more or less a representation of the raw
bitstream if you think about it. You can use RTTY for morse too, and out of
the box the streaming software and players have buffering built in. I just
find it funny that you're taking a single-bit bitstream and turning into a
potential 48kbps 32-bit audio stream LOL.

Has anyone else done something maybe with an arduino, esp, or Pi? Read pin,
send 1 or 0, maybe using telnet? In this example there would be no
buffering. Since raw RTTY has no buffering either I'd be OK with whatever
errors pop up.

An example use case might be to have an established current loop from my
detached garage to my house via WIFI, but I don't want to send data
specifically using a protocol, I want a raw actual loop, so if I attached a
morse key and key'd down, thats what would happen on the opposite end.

Thoughts?
