Hello friends. I've spent the last few hours trying every little
tricksy I know to get a PCI modem working under Linux. Actually it's my
roommate's computer, not mine. He has a Creative Labs Modem Blaster
v.90 PCI modem. It works under Windows. It uses Com3 there, and
strangely, interrupt 9. Which is also apparently used by his i740 video
card, but they both work fine in Windows. I'm 95% sure this not a
"winmodem." Actually, I told him to try to sell it and aquire an
externel modem, but I just want to know if this is even remotely
possible. I did several searches on Dejanews for PCI modems under Linux
and found scads of people asking this same question, but no answers.
/proc/pci sees a "serial controller" at IRQ 9. This is right.
/proc/tty/driver/serial seems to also see /dev/ttyS2 at IRQ 9.
I do:
setserial /dev/ttyS2 irq 9 uart 16550A // etc... etc... I know that's
right
setserial -bg prints out everything right, including /dev/ttyS2, except
it prints IRQ 2 instead of 9. I know they are normally cascaded and
linked together.
But of course, I can't initialize the modem in minicom ... it's just not
talking to it.
I wonder if anyone knows if this is even possible, and what I might be
missing ... I've read PCI & serial HOWTO's, and seem to be doing
everything by the book. I just want to know if PCI serial controllers
are even supported yet (in Linux 2.1.125) and if there is something
special I have to do to activate them.
any help is appreciated ....
