I remembered cu is next to vi in the “impossible to quit software” list.
@adi@twtxt.net Hmm, I never heard of that one before. The debian package description says:
The cu command is used to call up another system and act as a dial-in
terminal (mostly on a serial line). It can also do simple file transfers with
no error checking.cu is part of the UUCP source but has been split into its own package because
it can be useful even if you do not do uucp.
I’m wondering what are you using it for?
@lyse@lyse.isobeef.org I personally used it to connect to embedded dev boards via serial connection (dev boards I noticed come with a lot of crap frameworks and tools. I just used cu and plain C). You can also use it for https://man.openbsd.org/vmctl.8#console.
You quit cu by pressing ~.. If that doesn’t work, “just hit Enter a couple of times before the combination” (read it on some forum).
[…] It is now frequently used for tasks such as attaching to the serial console of another machine for administrative or debugging purposes.
@movq@www.uninformativ.de Heh! I think I just closed the window or just kill-ed the process whenever I got that laggy, if ever, that I couldn’t quit with just exit.
@adi@twtxt.net Ah, I see, thanks!
