Hi everyone,

My name is Greg House and I'm fairly new to this list.  Been reading on the
web archive for awhile, but just got on last week.  I also just started
working with Linux.  While I've been experimenting with several different
distributions on my PC, the current one is Slackware (3.5).

I've been trying to set up a PPP connection to my ISP (Southwind) and I'm
having a little trouble.  I apologize if this is a FAQ, but I've looked
around a bit (PPP HOWTO, PPP FAQ, Serial HOWTO) and haven't found this.

I have a modem (Harmony 56Kflex) that's set up as COM4 to DOS, it's IRQ 9,
I/O address 0x2E8.  It's been over a year since I built this PC and I think
there was some conflict that made me move the IRQ out there, but I don't
honestly remember what the reason was.  Anyway, that's where it's at right
now.  My understanding is that since this is a "nonstandard" IRQ, I need to
use setserial to configure the IRQ for the device.  I tried this and it
didn't correctly change the IRQ.

I use the command:

/sbin/setserial /dev/cua3 irq 9

This changed my IRQ to 2...  I don't understand how that happened.  I edited
rc.serial (in /etc/rc.d/) and commented out the setserial line that
autosensed the IRQ and put in one to explicitly set it to 9.  When the
system is rebooted, setserial -a (or -b) says it's set to 3.  If I use the
setserial command above, it sets it to 2.

What am I doing wrong?
