It works, but there is no autoscroll, which limits its usefulness.

Very simple and easy to use, however it is missing an auto scroll feature which is crucial for a serial monitor.

How to force sending CRLF (\n)? Launched in Chrome browser Version 77.0.3865.90 (Official Build) (64-bit) on Windows 8.1 Home to a USB device COM3, which works with e.g. putty. The problem seemingly is that CRLF (\n) is not sent; the device "sees" text (as confirmed by subsequent putty connection) but does not respond unless/until \n is detected..

Captures data off an inexpensive USB GPS puck. Works fine. Acer C720 chromebook

Buffer rate on the Output is slow and the input shell gives no interaction similar to Beagle Term (i.e tab for command list).

Existe uma falha fatal: Depois de abrir a porta, como eu faço para fechá-la? Mesmo fechando o app a porta continua presa pelo aplicativo

I'm an engineering professor and often demonstrate embedded programs (in both mbed and Wiring (Arduino & Energia)) during my lecture. This extension works very well for this. The minimal interface is an advantage is my application. If I want more features and flexibility I use Tera Term.

Writing this review in swedish. Appen funkar helt ok. Saknar autoscroll så om du spottar ut data med hög fart så blir det svårt att läsa den. Man kan alltid copy/paste in i en texteditor för att kolla loggen. En väldigt enkel app så förvänta dig inga underverk, men den gör sitt jobb och visar tillgängliga portar och data som flödar. Thanks! =)

Works fine with a Chromebook as a demo. I wish it would scroll better.

I tried to Download the SM App on my Android Tablet using Google Chrome but it doesn't download the same as on my laptop & can't get it to work! Any ideas?

I have an Acer C720 ZHN Chromebook. Connected to an Arduino streaming output via USB at 9600 baud, the window does not scroll with the output, and homes on each new line so it is impossible to see the newest received data. Please add an auto scroll and window line limit.
