I am trying to use a USB optical probe where, in the media settings, the port shows as Prolific Technology, Inc with the following configuration: Baud rate 9600, Data bits 8, Parity None, Stop bits 1, and Chipset Prolific. However, when I click Read and Open in the Android application, I get the error Failed to open serial port. On Windows, the same setup works fine and data is fetched successfully, but it fails on Android.

Using the API's provided, how to prepare the Profile General to look like in your example below? What need to be done before calling cl_write() to prepare array and structures.

Wait Time: 30:00

Address Type: Default

Physical Address: 1

Logical Address: 0
