How many serial ports does it have?

Sometimes just adding a definition of the chip may help. Let's try it
(assuming that the card has four serial ports):

Is it the same card?

Both kernel modules (uart and puc) should be compiled in kernel
or loaded as modules. And I don't use kernel module sio for a long
time. Since uart and sio use the same hardware they shouldn't be
used simultaneously. I used to have lines at my kernel:
-----
nodevice sio
device uart
device puc
