    Not if implemented correctly.

    Set the retry counter to 5 at the beginning.

    if you get 0xfe: decrement retry counter,
    if 0 :
    no keyboard connected. Give up.
    else
    Just immediately resend the last command
    else
    set the retry counter to 5 again.
    process returned code
