For some retro feeling I grabbed my old modem and attached it to the phone line. Minicom and dial-out work but now I'd like to allow dial-in with a getty waiting on the line.
Systemd has a serial-getty@ service which uses agetty but that doesn't work. It seems agetty is just not suited for that job although the manual page claims it to be. But I couldn't get agetty to wait for an incoming call, answer it, and then send the login prompt. Instead, it always immediately sends the prompt, execve()s to /bin/login which then terminates after a 60s timeout. I've now installed mgetty but there is no systemd service file for it. Should I change the serial-getty@ service to use mgetty or should I create a new service for it? In case of the latter, does it suffice to only add the .service file or do I need anything else? Steve
