The system is detecting the card, assigning a serial driver to the modem, but declaring it to be an ethernet device. In my view there are several possibilities: 1. Some configuration file I am supposed to create to tell the system how to configure the card. I noticed some alias statements in /etc/modprobe.conf related to the card, including one that aliases the serial driver serial_cs to eth1. I tried placing a file in modprobe.d with a statement aliasing serial_cs to ppp0, but that didn't help. 2. Some database with an error in it referenced by the configuration software. 3. A bug in the pcmcia hardware detection and/or the network configuration software. I've tried to look at the code in kudzu.py and in system-config-network to see if I can find a bug. If there is a bug, that's where it probably would be, and I see a lot of relevant statements, but the code is too complicated for me to easily understand. Stan Klein
