[hylafax-users] Trouble Setting up multiple modems on RedHat 7.0

[Douglas Younger <dyounger@corp.earthlink.net>]

Hello,
   I am trying to set up a fax server machine with four internal PCI 
modems. I have USR/3Com 3CP5610A modems which are not winmodems. I tried at 
first to just get one modem set up, and using the standard kernel supplied 
with RH7.0 (2.2.16 & patches), I was having no luck at all. I also tried to 
compile 2.2.17 (which is a feat in and of itself with RedHat shipping a 
beta gcc that won't compile kernels), and was still unable to access the 
modem.  So, I got the 2.4.0-test12 which is the latest beta kernel (the 
modem box says you need 2.3.x or better, which is funny, because 2.2.x is 
the current "stable" revision). Anyway, I finally got a modem setup & 
communicating with minicom. So, I put in the other 3 to see if I could 
configure them. Well no luck. I seem to get a whole lot of resource 
conflicts in the boot sequence. Looking at /proc/pci it only listed 2 of 
the modems, And /etc/sysconfig/hwconf (from kudzu) lists 3 ?!? I tried 
dropping to only 2 modems and I still get conflicts. With more than 1 
modem, I can't access any of them.

The modems are supposedly plug & play, and I did compile PNP into the 
kernel. In bios I have both on board comm ports disabled as well as LPT to 
try to free up as many IRQ's as possible. Also, the on-board sound is 
disabled. I couldn't find any way to disable USB in the BIOS. The box 
itself is a Dell OptiPlex GX1 P3-550 non-scsi.

I've searched RedHat's site with no luck. 3Com's site is absolutely 
useless. I've found a few pages that pointed me in the right direction to 
get one modem set up, but I cant find anything with info for setting up 
more than one.

Any suggestions or references would be appreciated.
