Please provide more detailed hardware description and a output of 'cat /proc/isapnp'. IMHO this problem can be solved easily.

Thank you for being so soothing. As you could probably notice, I was a bit frustrated.

On the first machine, with the modem (note that I ran isapnp manually, since this modem is my net connection!):

Use of isapnptools package mixed with kernel 2.4.x ISA PNP subsystem is asking for trouble. Move /etc/isapnp.conf file to some other place and try to reboot.

Hmm, looks strange to me, it seems that serial driver found your modem and configured it as /dev/ttyS2. Did you try to test it with minicom for example ?

Hi,

please test the attached patch (2.4.6-ac2), it should add support for ISAPNP PCMCIA card.

Best regards.

PS. Is your modem working now ?
