Re: [aclug-L] Modem configuration question

[Brian J Chapman <bchapman@xxxxxxxxx>]

The PC architecture was designed in the Dark Ages and has plagued mankind
ever since. IRQ 9 _IS_ IRQ 2, i forget the technical reason at the moment
but basicaly just think of 9 as a mirror to 2 and never set anything on
it otherwise strange happenings may abound.
