Uninstall Patch Versions

The Perle-Serial driver version 2.0 and higher is a standalone kernel module. If previous patches have been made to the kernel for the UltraPort card, then these patches must be uninstalled before the new driver module can be installed.

1.Find the UltraPort patch files to the kernel. Remove the patches from the kernel source files by entering the following commands:

cd /usr/src/linux

patch –R –p1 < <path to patches>/<patch file>

Note: If more than one patch file was added, then remove them in the reverse order that they were applied. (i.e. If the ultraport.patch-x.y.z-2.4.x was added and then the ultraport.IO8mode-x.y.z-2.4.x was added, remove the ultraport.IO8mode patch first.)

2.Recompile and install the kernel based on your specific system. For help on this procedure please refer to your LINUX documentation.

3.The new Perle-Serial software can now be installed
