Hi Steven,
The kernel does detect the serial port.
dmesg gives:
ttyS0 at 0x03f8 (irq = 4) is a 16550A
ttyS1 at 0x02f8 (irq = 3) is a 16550A
When I plug a modem in ttyS0, and do `cat > /dev/ttyS0`
I can see that the modem is receiving something.
Concerning /dev/cuaX, the new kernels (>= 2.2) do not use it anymore.
Everything is done through /dev/ttySX
Best regards,
Arnaud
