Exactly. The "real" NS16550s don't have builtin hardware flow control
either. Steve Nuchia's USENET-II serial board does implement hardware
flow control with a clever hack. I find it a bit price for a 16550
four port board, though.
Perhaps the fifo trigger level should be set to 4 instead of 8 for the
higher speeds in the com driver?

You don't need to quote my .signature. Everyone has seen it by now.
Besides, it doesn't add anything to the current thread.
