Hi, Thanks all for your kind help.
I'm doing few operations using serial port. So, I've done a small serial driver by referring FTDI code, and I'm accessing this using serialIO from my application. and it was working fine with older EFI shell. Now I'm using the latest UEFI shell. Now It's working fine for first time. Then if i do any removal and connect of serial port, there is a mismatch in "Handle index" value between the one i get in my application, and the one i get in "sermode" command. I'm using the same code as sermode code, but still, for the same Handle value, the handleIndex value is deferring. Whether ConvertHandleIndexToHandle and ConvertHandleToHandleIndex functions are giving issue? What could be the reason? Thanks again.
