It will only go "online" if you connected pin 1 to something (pin 4 at
the other end would be a good bet). But I don't think this is
necessary, it's just for information.

The interrupt is only registered when the port is in use. You should
see it in /proc/interrupts when minicom is actually running. Does
"dmesg" mention any serial ports? It should say something like "ttyS0
at 0x3f8 is a 16550".
