It offers features such as file transfer using X/Y/Zmodem and Kermit. It can replay recorded sessions which is very helpful during support calls with vendors/customers. These features are normally found it commercial offerings. It is also regularly updated and is a small download. A must for any network administrator's toolkit.

It is a responsive software that shows the incoming data on the edge or terminal software. We can now set serial port connection without any hesitation.

I love that Teraterm is open source and is very feature rich. It handles serial connections super well through the drop down box as well as all of the other features you would expect from a terminal emulator.
