Minicom is to Linux/Unix as Hyperterminal is to Windows.

In minicom, the key-combination is ctrl+a f

    You can also use screen, as I do in OS X.

    Something like this:
    screen /dev/tty.KeySerial1 9600

    with a keyspan serial adapter works nicely.

    Fantastic, Jk!

    What is the “Break” key-combination in Screen?

  3. jk February 27, 2008 at 9:56 pm

    Well, with Screen, it’s unique. You have to execute the screen command (by default ^a) and THEN execute the break, which is, at least in my version, ^B

    It seems to also show that I can use ^b instead – so case indifferent.

    So, it’ll actually a multi keystroke, ^a ^b

    I finally figured that out and it made my life so much easier. Of course, screen is horrible for keeping histories of what is scrolling by and reusing it. It’s not something I can use for a ‘show tech’ really, unless I’m logging the session with terminal, which I don’t do by default.

    But it’s built in and every mac laptop has the ability to do it.

    Oh, and ^a ? will give you screen’s help page.

    Excellent! I tried “screen” on my mac at home over the weekend. You’re right.. you lose history, which is a major PITA. But still, quite cool.

    Had a problem exiting, though. I basically used ^A Z to exit, but apparently, that just brings me back to my terminal. By screen process was still running in the background from ‘ps aux | grep screen’ so I had to ‘kill -9’ it.

    I just close the terminal window in question. With Apple’s shortcut keys for terminal, it’s trivial to open a new one.

    And I’m sure there’s a way to make a little shortcut to a script to just click and open a new one as well. I’m only on console a few hours a week these days, not like before when it was 30 hours a week, so I don’t bother making it bette.r 😉

    Excellent! Thanks for the outstanding discussion!
