A standard terminal emulator.
It is open source and supports SSH2 protocol and UTF-8 display.
Telnet, SSH and console connections are supported.
Supports serial port connection (PC communication).
* The image introduced here is an old version of Tera Term.
The serial port setting specifies the COM port you are using. If you are using USB-Sirial connection, open "Device Manager" and check what number of COM has been assigned.
●Serial port setting
Specify the serial port settings according to the network device to be connected. For example, in the case of Cisco router, set as shown in the figure below.
If there is no problem with the connection, the characters will be displayed as shown below.
PuTTY is a terminal emulator along with TeraTerm developed and published by Simon Tatham. PuTTY is widely used because it supported SSH2 earlier than TeraTerm.
It can be localized to Japanese, but it needs to be patched. Until you get used to it, I think it's easier to use if you translate it into Japanese.
For Japanese localization, please search on the Internet.https://www.chiark.greenend.org.uk/~sgtatham/putty/index.html
