Serial emulation in OS X Terminal Using screen

Every once in a while, I need to connect to a serial/TTY device in OS X. I could get a terminal emulation app like ZTerm, or fire up the Arduino IDE (which has a simple terminal emulation interface), but sometimes it's just easier to open up Terminal.app and go from there.

The screen command can work as a simple terminal emulator. Here's how that works

$ screen /dev/[TTY device] [baud]

For example, here's a concrete example

$ screen/dev/tty.serial101 115200

Alternatives

screen is available on all OS X systems, all the time, so it's a fine thing to fall back on. However, it's not exactly full featured. There are several alternatives, but I like picocom. It's small, useful and reliable. It can be installed with brew picocom if you've got Homebrew.
