Cisco Switch/Router programming using Arduino?

Hello all! I have had a strange idea I want to do, basically I can write the whole code, it's not a big deal, it's just the one part I cannot figure out is how to interface with the hardware:

So, I want to build a device that will program a Cisco Switch/Router, I know I have to use 9600 baud, 1 stop bit, no parity, and a rollover cable, that part is clear, however, the problem is, I do not know how to connect the rollover cable to the Arduino. The rollover cable is a standard DB9 connector with a RJ45 jack on the other end.

Any advice would be greatly appreciated! Thanks! you were looking for this or something else?

Yea, basically I need to fully replicate a RS232 DB9 communication to attach a rollover cable to the arduino and then send and recieve commands.

If I were to use tutorial, would it allow for full functionality 9600 baud communication?


I personally have never used software serial so I am not sure but that seems logical

I hope it does :stuck_out_tongue:
The only limitation now (after I sat and figured it out) is I hope that the rs232 has all the functionality of the PC counterpart (the arduino output I mean)

It should work. Cisco consoles work fine with only three wires (rx, tx, gnd) Don't be cracking my routers, though; it wouldn't be much of a challenge; cisco has always assumed that physical access to the console port means that its YOUR router.

If you can think of something useful to do connected to the cisco console, let me know, and we'll see if I can put you in touch with people that might be interested...
