I'm not sure why it is reported that way, but that seems to be the case
in the 2.4 kernels. (I just noticed it is changed in the 2.6
kernels--but that is not your problem.)
(Hey, it changed in the 2.6 kernels!)
ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
(This is the 2.4 series)
ttyS00 at 0x03f8 (irq = 4) is a 16550A
ttyS01 at 0x02f8 (irq = 3) is a 16550A
