Default Console access to routers using USB to Serial Connectors - 09-10-2009, 11:40 PM

On Windows platform I use SecureCRT - to access routers/switches through serial console -

I discovered recently that it is equally easy to do the same from macosx -

You can get any Prolific PL 2303 Chip based USB to Serial connector -
Then - use this driver with support for sending "Break Keys"

PL2303 USB to Serial Driver for Mac OS X | Get PL2303 USB to Serial Driver for Mac OS X at -

(Solaris Notes OS X: Send break via serial/usb converter - Source for the link above )

Install Driver -

Reboot -

With USB to Serial connector hooked up -

Open Terminal -

type ls -l /dev/tty.*

among others - you should see an entry like /dev/tty.usbserial or /dev/tty.PL2303-0000203D -

Now to access your router connect console cable to the USB serial connector
and in Terminal type -

screen /dev/tty.PL2303-0000203D 9600 (connect using baud rate 9600)

^c (Control c - to get connected to the serial console ) -

^c-a ^\ to disconnect the session cleanly - (Control-a Control-\)

y to the prompt to quit and kill all windows -

I have verified this with Cisco Routers and Pix firewalls -
I was also able to send break signal to interrupt boot sequence - ( ^-a ^b) -

Hope you guys find this useful.

the PL2303 rocks. it's been the iron-standard for doing anything over 232 for years. I've had many, connecting up linux/mac and even had a psion just to console to IOS

Only problem is, the driver was not done well and Prolific is taking their time making a 64-bit enabled driver. The older source, even the improved clone on sourceforge, are all using 32-bit ints and porting that does not look easy.

Screen works good. I have a few programs such as VirtualSerialTerm and other apps I've compiled/found on sourceforge/github and the other various sites. Most just put a guy on a vt100 but some do offer increased control that is sometimes required for fussy hardware, like changing flow/etc.
