Hello,
I have a small application written in b4j that connects to a device over a serial COM Port (USB Serial based on CP21x02). Everything was perfect until last week, when the communication stopped working over USB/Serial. I've suspected an issue with the device or the USB/Serial Interface, but no issues at all with other applications and the same device/interface.
The problem exist on other systems too with the same Windows version. The app still works ok over a Serial Bluetooth connection.
Currently I'm using Windows 10 [Version 10.0.18363.815] and jdk 1.8.0_251
Do you have any idea what can be the root cause?
Thank you.
Dan
