300bps is fine but 1 my cell or mobile mic port is a mic port, not a line in and 2 you need Linux im running windows but I can use a VM also I tried this but with Skype and it did not work but the 73VHC942N looks good I was going to use old corded phone connected to a 9 volt battery and to a modem like this

I want to build an acoustic coupler so I can put a retro handset for my mobile on it and dial into my raspberry pi dial in server and get a shell so I can, ssh into other computers, use a command line browser, or whatever else you can do from a command line.

Thanks this worked minus the inittab which i do not have but a friend helped me use system ctl which works now to try and build an acustic coupeler so I can dial in over my mobile e.g http://eric-ode.tripod.com/acoustic_coupler.htm and https://youtu.be/uQqWHLZjOjA

yes I have a usb to serial cable connected to the modem I would like it to be something like this or this also I still have a copper line

hello I would like to make a dial-in server, not for internet but for a Linux terminal i want to run it on a raspberry pi running rasbian I have been looking for ages I found mgetty but I can't find a tutorial

Ok, but what if i put the swap file on an optane drive?

As the title says can i run a virtual box vm on just swap space/pagefile
