Speakup and PCI Express Serial Cards

[Trevor Astrope]

This is what I am thinking as well. Just fyi, the card doesn't use any 
special drivers and is compatible with the linux serial driver, which is 
built into my kernel. The company supports linux as well. This is why I 
bought it. It was just supposed to work. <grin>

Here is the output from setserial:

/dev/ttyS0, Line 0, UART: 16950/954, Port: 0xcc00, IRQ: 16
         Baud_base: 115200, close_delay: 50, divisor: 0
         closing_wait: 3000
         Flags: spd_normal skip_test

Does speakup get the serial port address from the bios? Since the card 
isn't built-in, it would make sense that speakup can't find it, if this is 
the case.

Using lspci, it does list the card and the serial port address and irq.

Btw, I did try changing the uart to 16550A, as the card supports this uart 
type, but still no go.

Thanks,

Trevor
