Hi, Thanks for the response. I have explored the option of FIFOs, but the issue is I need Full duplex support from the devices. In that case I will have to use two FIFOs for each device. So, it would be good to know if there is any better option. Also, I was thinking of multiple virtual device nodes with single UART. But, I want to know how do I have these layers communicate? multiple virtual ttys with single UART work? Please suggest.
