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!
