How much was the card, and where can I get one?
I've been wanting a way to use my PC express slot in my laptop, hoping 
someone would make a synth to plug into it.  So far I have only found PC 
express video cards.
I would use one of these for my DecTalk synth, serial type.

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
