Hey people note ..
ungrab-winmodem.ko, that is essential in the process of setting up a PCI modem driver, is missing in the package in which it must be found.
The package is slamr-2.6.22-14-generic.tar.gz, found on http://linmodems.technion.ac.il/packages/Smartlink/Ubuntu. Sasha Khapyorsky is the author of this driver for this HSP56 micromodem 688T of Oasis chipset.
Upon gunzipping and tarring, the resulting folder has a setup script, in which there is a line as follows:
modprobe ungrab-winmodem
but unfortunately, there is no ungrab-winmodem in that folder. The script thus fails to install the driver on my Edubuntu 7.10.
Somebody bring it to his notice.
