I use GNU screen for that. Looking at cu, it looks to be just as tiny and has ssh-like tilda-escapes, including "~." to disconnect. Nice, gotta try it out, thanks!

I got used to using minicom way way back. Has a nice TUI and can do stuff.

I only moved to using screen about 2 years ago after over 2 decades of minicom

cu might be good for anything that you have a fixed config, otherwise I'll just go with minicom

What would you suggest? Personally I find cu the closest to ssh in ergonomics to any of the tui serial terminal programs, and it’s easily available across unixes like FreeBSD or Mac OS, which is a bonus.

cu is the regular way of doing it

I don't see the problem. Minicom and even picocom are bloated compared to cu

One comment [0] highlights a point in favor of the current implementation:

> create a lock file for every dial-in line to prevent its use by programs looking for a dial-out line.
