I got de pctel driver "pctel-0.9.7-9.tar.gz" at http://linmodems.technion.ac.il/pctel-linux/ It compiled well. At insmod -f pctel.o works. At insmod -f ptserial.o i got many unresolved symbol. Folowing the readme files I try fixscript but not work. Compiling again the kernel. But not works. I use 2.4.31 kernel downloaded from kernel.org. I use slackware 9.1. I had 2 sources(4.31 and 4.22). After I removed package kernel sources e kernel header(2.4.22). I try compile de pctel sources but not compile anymore. Says usr/errno.h not found and other include files. But I see these files there. What´s wrong ? thanks ---------------------------------------------------------------------------------- KATATUDO sua melhor pesquisa na internet.
