Hi, Marcio My laptop is a Toshiba Sat 2540CDS, with a similar (i think so) internal winmodem; sometime ago i did try this binary module (releases 5.65a and 5.68) with slink and kernels from 2.2.11 to 2.2.16. At first i got 3-4 succesful ppp connects, but then i got my first kernel Oops :( I don't know what the problem is (my logs didn't show nothing useful, at least for me :), but i don't remember any relation with pcmcia (like you, i'm using an ethernet pccard). Anyway, this is from my last Oops: Jun 12 21:00:10 localhost kernel: CSLIP: code copyright 1989 Regents of the University of California Jun 12 21:00:10 localhost kernel: PPP: version 2.3.7 (demand dialling) Jun 12 21:00:10 localhost kernel: PPP line discipline registered.

Do you want to dial again after the kernel Oops?

I don't know if the problem is with the pcmcia drivers; for sure, the problem is an stupid closed device with no public specifications, and a binary only module with no code to see what is wrong. If you can, get a pcmcia modem card... -- David
