Error instantiating SerialComManager on Windows 10 32-bit OS

[Alex Olsen]

Hi Rishi,

Thanks for providing and maintaining this great library.

I've developed a Java application with releases on Mac OS X, 32-bit and 64-bit Windows.

I'm using the most recent version of SerialPundit, and I've added the following JAR files to my library classpath:

- sp-core.jar

- sp-hid.jar

- sp-ioctl.jar

- sp-tty.jar

- sp-usb.jar

The application works flawlessly on Mac OS X and 64-bit Windows.

However, when testing the application on Windows 10 32-bit OS I get the following exception when instantiating the SerialComManager:

SEVERE: Error instantiating serial port manager:

Any help in correcting this exception will be greatly appreciated. Let me know if you require any additional info.

Cheers,

Updated new sp-tty.jar in github repo https://github.com/RishiGupta12/SerialPundit/tree/master/prebuilt-release

Thanks for the prompt reply. The above issue is resolved.

However, a new exception has arisen inside sp-tty.jar when trying to list available serial ports on 32-bit Windows 10:

SEVERE: Error collecting available serial ports.

I have found a fix to the latest exception. It was not originating from the serialpundit jar files. Thanks for your help Rishi.
