ttyS2 in ttyS0 imata isti IRQ (obicajno irq = 4). Zelo verjetno imas na
ttyS0 ze neko napravo.
V 2.2.* kernelih  je deljenje irq-jev mozno, vendar je za to potrebno v
kernel vkluciti: 

Character devices:

"Extended dumb serial options" (CONFIG_SERIAL_EXTENDED):
If you wish to use any non-standard features of the standard "dumb"
driver, say Y here. This includes HUB6 support, shared serial
interrupts, special multiport support, support for more than the
four COM 1/2/3/4 boards, etc. 

in
"Support for sharing serial interrupts" (CONFIG_SERIAL_SHARE_IRQ):
Some serial boards have hardware support which allows multiple dumb
serial ports on the same board to share a single IRQ. To enable
support for this in the serial driver, say Y here.
