Re: Issue in ConvertHandleIndexToHandle and ConvertHandleToHandleIndex

[GN Keshava <keshava.gn@gmail.com>]

Thanks Jaben.

I expected this answer. :) Definitely I can't do that as of now.

But do you think this would cause mismatch between the handle index that i
get in my application? The handle index I'm getting is differing, even if
the handle value is same.

And, could you suggest any other ways to fix this, other than embedding my
app into the shell?

Or do you suggest my temporary workaround , in which I'm embedding my own
sermode functionality inside my application ? The functionality​ is working
and I'm able to use com port. But it's annoying to have different
information in app than a shell command! :(

Thanks again.
Regards,
Keshava
