Serial USB Terminal Customer Insights

1. I'm using it to monitor iand setup my diy ev conversion.Works great to log serial port data!Seems like a very straightforward, functional term app with USB OTG support.

2. Sending a 0x0D carriage return to my tablet results in a linefeed as well so the data sequence moves down the page with each character received, instead of the new data overwriting the old.Works great for my needs.

3. I wish that it auto detected my serial port and it doesn't work with the HP network switch's help function.

4. Plus with it being mobile, I can easily debug in the field if needed.I am using this app to connect to a Terminal Node Controller (TNC).

5. The limitations of a phone's on-screen keyboard are mitigated by the costom macro feature which permits otherwise-untypable control characters to be sent either instantaneously by themselves or inserted into a longer message.

6. It's still very new to me but seems fine so far.Combined with the right adapters (like USB-C to USB-A,) this app turns your phone into a very useful engineering tool for embedded systems development.

7. It connects ok but I have to keep depressing carriage return in order to get the buffered data in the TNC.

8. I guess I need to stop relying on the help menus so much.Fantastic App! Just what I needed for doing some testing on some new hardware design.

9. One problem is the inability to move the cursor back to top left in order to display a count sequence for example in the same space on the screen.

10. However, it did really well at displaying the terminal properly and allowing me to enter the command I needed.

11. This does not happens whith a PC terminal program like Teraterm, Putty, and others.
