I have tried to get these serial line added to my Linux machine (RH 6.1 with
2.2.14). I do not understand what the trouble is.
Output from setserial
=========================================================
[root@gateway rc.d]# setserial -gav /dev/ttyS?

The card I am adding is http://www.siig.com/io/i_o_expander_4s.html.
I am setting port A to 3E8/IRQ4 and port B to 2E8/IRQ3. The unboard Serial
ports are 3F8/IRQ4 and 2F8/IRQ3. This should be the defaul config. Will
interrupt sharing work accross different cards? What could I do to enable
these serial ports ??
