About this app
'Serial USB Terminal' is a line-oriented terminal / console app for microcontrollers, arduinos and other devices with a serial / UART interface connected with a USB to serial converter to your android device.
This app supports USB to serial converters based on
- FTDI FT232, FT2232, ...
- Prolific PL2303
- Silabs CP2102, CP2105, ...
- Qinheng CH340, CH341
and devices implementing the USB CDC protocol like
- Arduino using ATmega32U4
- Digispark using V-USB software USB
- BBC micro:bit using ARM mbed DAPLink firmware
To connect USB to serial converters, your android device must support USB OTG aka. USB host mode. Most devices support this today, but in case of issues check with one of the various USB test apps, if host mode is enabled in your android kernel.
All features in this app are free. In-App purchase is only used for the 'Donate' option.

Works well for me. Connected my Raspberry Pi Pico, to my Google Pixel 4a (5G) phone. Connection and subsequent connects were quick. At this time I am only receiving data from the connected device and am not sending data from phone to device. I am so glad to have this utility without ads or data collection. I tried other apps that did not work for a simple USB / serial connection.

No way to up arrow commands is a deal breaker for Cisco work. Up arrow scrolls through the last few commands in IOS. It is necessary to replay command strings to quickly modify several ports on a switch. Without this it makes modifications much more difficult. I could use this instead of a windows machine if this were possible here. It is the best one out there, but just is not enough to depend on for me.

I see. Accessing the remote history and showing the selected value in the input area is hardly possible, but I can think of an app local history, e.g. accessible with a history button or long click.
Have you tried to store your favorite commands as macro buttons?

I tried so many serial apps and this was by far the best. I wish that it auto detected my serial port and it doesn't work with the HP network switch's help function. However, it did really well at displaying the terminal properly and allowing me to enter the command I needed. I guess I need to stop relying on the help menus so much.
