Chris, It seems to me that this Modem is not really an Intel 537 Modem, but one disguised as one. Here's another user having difficulties: http://ubuntuforums.org/showthread.php?t=1183881 I run scanModem fake the PCI IDS you have sent and it reports Intel 537: === Finished firmware and bootup diagnostics, next deducing cogent software. === Predictive diagnostics for card in bus fake: Modem chipset detected on NAME="FakeName" CLASS=FakeClass PCIDEV=8086:1080 SUBSYS=1028:1000 IRQ=fake IDENT=INTEL537EP For candidate modem in: fake FakeClass FakeName Primary device ID: 8086:1080 Support type needed or chipset: INTEL537EP Since 2006, Intel appears to have ceased its modem code updates for Linux. The outdated official Intel support packages can be accessed through: http://developer.intel.com/design/modems/support/drivers.htm Beneficially, Philippe Vouters has been provided updates as the Linux kernel evolves. But intensive personal support is not feasible, see: http://archives.linmodems.org/24939 The code for the INTEL537 and INTEL536 chipset modems is now at: http://vouters.dyndns.org/Intel/ , previously http://x9000.fr Copies are also stored at: http://linmodems.technion.ac.il/packages/intel/Philippe.Vouters/ For Ubuntu Linux users with Intel 536 and 537 chipsets, there are driver installation packages available thru http://groups.google.com/group/ubuntu-modems Read DOCs/Intel.txt and Modem/DOCs/YourSystem.txt for follow through guidance. Which is a bit different from what you have sent: NAME="Modem: Intel Corporation FA82537EP 56K V.92 Data/Fax Modem PCI " When I see "FA82537EP 56K ", I have seen reports that sadly this modem is unsupported. Marv and/or Phillppe can confirm this, hope that they can let you know if this is sadly true.
