Thanks for posting all these articles - they are very interesting.
I will definitely try it out when there's something to try.
Have you any idea what you will do about the modem? Will you try and incorporate ModemManager / eg25-manager (if that's possible) or will you be building something of your own?
Also, this probably isn't relevent but have you seen this series of articles? https://www.nihaljere.xyz/words/summer_of_phone.html

Thanks and good luck

Thanks! I haven't started working on the Modem Driver. The articles look really interesting, I'll check them out :-)
