{ Support for the FIFO modes of 16550 and 16750 UARTs
{ Serial port bit rates up to 921,600 bits per second with 16750 UARTs
16750 -MIGHT- only be on PCI.... sigh...
Baud Rates
All standard baud rates up to 115,200 bits per second are supported for
all UART types. If 16550 UARTs are detected on a Quatech Enhanced Serial Adapter, the maximum baud rate increases to 230,400 bits per second. If
16750 UARTs are detected on a Quatech Enhanced Serial Adapter, the
maximum baud rate increases to 921,600 bits per second.
"Enhanced Serial Adapter". Bummer, said Pooh, as he dropped his roach in
the Honey Pot...
