===Windows===

To login from a Windows PC, you'll need an application for serial communication. The most common is '''PuTTY''' - free, open source SSH and Telnet client, which we'll be using for this example. You can download PuTTY from '''[https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html here]'''.

* First you must find out which '''Serial line''' (or '''COM port''') your cable uses. To do so, go to Windows '''Device Manager''' (you can find it easily via the search field or in the Control Panel). Find '''Ports (COM & LPT)''' in the device list and expand that section. Locate your serial device (depends on the type of cable) and take note of its '''COM port number''' ('''COM3''' in our example):
