    I have a doubt... I am not sure if you can have a full working
    solution to make all programs run using the virtual serial ports.
    Because, there *might* be some programs which actually use the 'in'
    and 'out' instructions of the processor directly from a user space
    program. (After calling iopl/ioperm etc to elevate their I/O
    privileges to directly use the IO ports) I dont think even a kernel
    change can help in that case...

    Is my understanding correct or am I missing something?
