Given that we're broadening our platform support having a > single serial driver seems preferable. I looked into it in 2003 but since I don't have any hardware, I wasn't the one able to do it. I think the fundamental problem is that the BRG is not part of the UART itself and needs a separate handle or even (tag, handle) pair to access. That's as far as I know the only big thing about the work. For me not having access to the hardware is a showstopper for looking into it myself. -- Marcel Moolenaar xcllnt_at_mac.comReceived on Thu Jul 03 2008 - 23:49:49 UTC
