Serial Port Access on OSX to Cisco devices
|26-Feb-2010||Posted by Sonia Hamilton under Cisco, Gnu Screen, OSX, Solaris|
How to connect to a Cisco device (or other serial devices) using OSX and a USB to Serial converter (eg ATEN). Googling, everyone says to use zterm, but I couldn’t get it to work (and zterm looks and feels like a toy).
This probably isn’t the “Mac way” of doing things, but </whatever>…
Install PL2303 USB to Serial Driver for Mac OS X, restart :-(
sudo port selfupdate sudo port upgrade outdated sudo port install minicom
Work out tty of USB-Serial converter:
ls /dev/tty* > pre
Plug in USB-Serial converter.
ls /dev/tty* > pst % diff pre pst 3a4 > /dev/tty.PL2303-00002006
Link up to make life easier:
cd /dev sudo ln -s tty.PL2303-00002006 ttyusb
Setup minicom, and use colour:
sudo minicom -s -c on
Setup defaults to:
- /dev/ttyusb (ctrl-A, O, Serial Port Setup)
- no hardware or software flow control
- init string empty (so garbage doesn’t appear on screen when you connect) – ctrl-A, O, Init string
- save settings as default (ctrl-A, O, Save setup as dfl)
Always use colour:
- add export MINICOM=”-c on” to shell rc file (~/.bashrc, .~/zshrc, etc)
Connect (sudo minicom), hit enter a few times, and you should be on the device.
