Hello, friend!
PuTTY is a free and open source program that integrates the virtual terminal, system console, and network file transfer. It supports multiple network protocols, including SCP, SSH, Telnet, and rlogin (original socket connection). It can also be connected to a serial port.
The device that uses PuTTY to log in must support remote login protocols (SCP, SSH, Telnet, and rlogin).
Thanks!
