Unhandled exception. System.NullReferenceException
See original GitHub issueI use the library, an error occurs only on Linux machines
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object. at RJCP.IO.Ports.Native.SerialBuffer.RJCP.IO.Ports.Native.ISerialBufferStreamData.get_BytesToRead() at RJCP.IO.Ports.SerialPortStream.HandleEvent(Object state) at System.Threading.QueueUserWorkItemCallback.<>c.<.cctor>b__6_0(QueueUserWorkItemCallback quwi) at System.Threading.ExecutionContext.RunForThreadPoolUnsafe[TState](ExecutionContext executionContext, Action1 callback, TState& state)`
Which leads to the failure of my program.
- This error does not occur often when the device is reconnected (physically).
- When it opens often, the port closes.

I analysed the code again, and the problem should not occur with 2.4.0. The callback for the handling of events has now a try/catch block (which would cause .NET Core program to exit, instead of causing an exception).
I’ll leave this ticket open for a few days, otherwise I’ll close it as fixed in 2.4.0 which is now a NuGet package for a month or so.
@ilrom Does 2.4.0 fix your issue?
