Andrew, The modem is potentially supported by slamr module slamr..ko + ungrab-winmodem.ko, as scanModem output states: Predictive diagnostics for card in bus 03:0c.0: Modem chipset detected on NAME="Modem: Motorola SM56 Data Fax Modem " CLASS=0703 PCIDEV=1057:3052 SUBSYS=1057:3020 IRQ=20 IDENT=slamr For candidate modem in: 03:0c.0 0703 Modem: Motorola SM56 Data Fax Modem Primary device ID: 1057:3052 Support type needed or chipset: slamr 1057:3052 has a Motorola chipset, poorly supported by Motorola itself However Zello discovered that drivers written to support Smartlink modems do support the 1057:3052 chipset!! It sufficed to add 1057:3052 to the list of modem cards recognized by the Smartlink slamr driver. There is a ungrab-winmodem driver used in conjunction with slamr, which must have 1057:3052 similarly added. See messages from Zello: http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00846.html http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00848.html and Alvaro Aguirre about the ungrab-winmodem fix: http://linmodems.technion.ac.il/bigarch/archive-seventh/msg00990.html For general guidance on ungrab-winmodem + slamr usage, read the DOCs/Smartlink.txt There is a package sl-modem-source providing a source code the modem driver , If can be searched for at http://pacakge.ubuntu.com. After downloading install under Linux with: $ sudo dpkg -i sl*.deb It is preferable to install the dkms package first. With DKMS support installed, driver updates with kernel updates will be automatically done. The modem is supported by the Smartlink plus the slmodemd helper utility. Read the DOCs/Smartlink.txt and Modem/DOCs/YourSystem.txt for follow through guidance. For 2.6.32-41-generic compiling drivers is necessary. As of October 2007 the current packages at http://linmodems.technion.ac.il/packages/smartlink/ are the ungrab-winmodem-20070505.tar.gz and slmodem-2.9.11-20080126.tar.gz If you can look for package as it is recommended here: ================================================ There is a package sl-modem-source providing a source code the modem driver , If can be searched for at http://pacakge.ubuntu.com.
