Although YAT is a nice software, I was quite disappointed by the fact that it is very limited to the concept of a terminal, unlike SerialTool (www.serialtool.com), which allows me to work better at a low level with serial communication.Reply from YATEdited 2025-02-28
Well, YAT says it is a terminal, neither expect a port sniffer nor an oscilloscope. PS: Questionable course of action to post questionable reviews here as well as at [RealTerm](https://sourceforge.net/projects/realterm) and [com0com](https://sourceforge.net/projects/com0com) to advertise some other tool. While YAT is open source with transparent change management and truly free, SerialTool comes with limited features and the option to pay for a [PRO license](https://www.serialtool.com/serial-port-license). That's similar to the [HHD Serial Port Monitor](https://hhdsoftware.com/serial-port-monitor) which also is a great tool. Isn't is even greater we all have the choice among all these great tools? -
Works very well for prototyping interactions with our custom USB HID based device.

By far the best all-around terminal on this planet.

This program is beyond amazing! I am still learning all its features, but WOW! I primariliy needed hotkeys to perform string sends and boy did this hit the ball out of the park! I will certainly find more applications that this will simplify, I'm sure! I'll give support a 5 because of what others are saying. I have not needed support yet, so maybe it's really a 10.

It's simply the best and most feature-packed terminal program out there. Also, the developer and maintainer, Maettu, is very attentive and always updating the program with fixes and improvements. Look no further.
