Well as far as the documentation says, apparently the
oboe chip supports both SIR and FIR, in what manner
this is accomplished I don't know.  I don't think it
is  controlled by a standard UART.

Well, I tried all the standard COM port settings and
had no luck.  when i load lirc_sir with com's 1 and
3's settings (irq 4, 0x03f8 or 0x03e8) or the fir
device's resources (irq 11, 0xffc0), the module loads,
but doesn't work.  with com's 2 and 4 (irq 3 0x02f8 or
0x02e8) the machine locks hard.

When I load the serial module, it only shows ttyS00. 
No other serial ports. Also when I run the irda
utility "findchip" I get no output.  I guess I might
try some DOS irda utilities next.

I guess this is my next option...

Thanks for your help,
