Hi,
I patched 2.6.10 and compiled in the parport and serial port options in menuconfig.

It still won't work:(

lspci -vv -s 0:b.0 shows:

0000:00:0b.0 Serial controller: NetMos Technology PCI 9835 Multi-I/O Controller (rev 01) (prog-if 02

Is that IRQ 19 real or bogus?

I tried: setserial /dev/ttyS2 port 0xdc00 uart 16550 irq 19
then: cat test > /dev/ttyS2
with various port and irq settings, but the command blocks for 10secs
then returns.
