Hmm.. Even my old USR Megahertz shows up as 16550A sio.. > > Isn't this what FreeBSD defaults to if it doesn't recognise your > card? It might just be a case of adding your card's ID to a > switch statement. Yes, it is. But there is no simple switch statement. UARTs don't provide explicit identification information to use with a simple switch statement, so the driver tries sending out a FIFO_ENABLE and a FIFO_RX_HIGH. If the unit responds with the FIFO_RX_LOW bit, it's a 16450. If it has the FIFO_RX_MEDL, it's an enhanced 16450. If it gets FIFO_RX_MEDH, it's a 16550, and if it's for FIFO_RX_HIGH, it's some type of 16550A. But, if the is no response at all, it's tagged as an 8650. R.
