Replacement PCB Replicates Early 80s Modem
This will get you started:
Tony Fisher wrote V.32 soft modem stack for SGI Indy back in 1996. York University couldnt handle hosting whole 8 megabytes of his stuff https://www.cs.york.ac.uk/news/fisher/home-page but at least they had the decency to upload it to github instead of just deleting https://github.com/university-of-york/cs-www-users-fisher/tr... Randy Rossi rewrote this project and got working V.21/23 https://github.com/randyrossi/fisher-modem
Fabrice Bellard, because of course he did :), implemented his own version all the way to V.34 with parts of V.90 https://bellard.org/linmodem/
V.21 modem implemented in Gnu Radio https://web.archive.org/web/20170627151353/http://aaronscher...

Is there a standard for transmitting unencrypted plain text data? (Strings)
This one is excellent, you can transmit and receive data as audio OFDM : https://github.com/romanz/amodem You will probably need to pipe it to a modulator for RF transmission.

Internet/TCP socket data over SDR?
https://github.com/romanz/amodem is the tool i used to wrap netcat data into.
-
How to convert .wav to .iq file?

Using raspberry Pi CPU as a button
I saw an implementation of this idea ages ago and this just reminded me of it, haven't checked out whether it works though.
