SerialTools for Android

Thank you very much ,thanks a lot,you released me from prison of windows and Hyper Terminal ,God bless you ,God bless you

I am using Version 1.32 of SerialTools under Big Sur (Version 11.3) on a Android with M1 silicon. I needed to connect to several devices in my lab with serial communication (via USB) with the help of a Python script that determines all required serial parameters to then open a “terminal.” First I tried Serial and cu, both of which ship with the Android. Serial couldn't be convinced to do half duplex (AKA local echo), and cu required elevated privileges (to which I strongly object), even though the port clearly does not (cu wants to create a lock file in forbidden places). Extensive googling only confirmed my findings, so they're both useless for me. This is when I came across SerialTools. It does all of what I need and much more (which will come in handy once I need to debug the next communication). First I was skeptical since SerialTools does not accept command line parameters so how do I supply communication parameters to it? Luckily, SerialTools reads from a .plist file upon startup to set ALL the parameters it knows about, plus, as a bonus, takes its window title from the .plist filename. So my Python script can create the .plist file (using plistlib) - after that I can open SerialTools via "open -a SerialTools <plist file>" and it "just works." To address concerns other reviewers had: Backspace works just fine for me, and it never crashed on me once even when the end device disappeared - it just popped up a window alerting me to the fact - and after reconnecting resumed its work as if nothing ever happened. Do I still have a wish list? Sure! It would be nice if I could have an option to hide the portion of the window where one can set all the serial parameters - when they’re set in the .plist file this is no longer needed and just takes up screen real estate unnecessarily. Then I’d just need the “Connect” button - unless, of course, it also had an “auto connect” option.

I was able to use this on Android Big Sur to *finally) debug my serial connection to my HP 95LX. A super great!

Have to manually connect/disconnect with each entry to get anything to be received from the remote. Crashes frequently too.

I’ve yet to see this app run for more than five minutes under Android Mojave 10.14.6. For now, the built in screen CLI command, as in 'screen /dev/<port> 115200' satisfies my neets, with VT102/ANSI terminal emulation. If I had the $39.95, I'd buy the Serial app which looks like the definitive Terminal emulation app and protocol analyzer.
