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!
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.

Whyyyyyyyyyyyyyyy
There are a million better ways of doing this.
