Release Notes for HiSax 1.2 Supported kernels : 2.0.X HiSax_1.2.patch is a linux kernel patch (against 2.0.22, it also works with 2.0.23 and should work with all 2.0.X) After patching you have to run make config (or menuconfig) and have a look at the new isdn options. This is a interim package, here are only the necessarily changes in isdn_common.c for hisax. The whole isdn part has many changes yet, but it seems, that here are also new bugs in it. A ALPHA driver with all new stuff is also available as ALPHA/HiSax_1.2.alpha.gz. !!! Attention this is very untested !!! For more informations see README.HiSax.
