Hi, I have a linux box with red hat version 6 with ISDN connection. While connecting to the net, i get an error message ppp_tty_ioctl: invalid ioctl: 5403 ppp_tty_ioctl: invalid ioctl: 5403 and system gets hanged. I checked the modem and its working fine. Dont know what to do as iam not able to connect to the net. Any help in this regard is most welcome. __________________________________________________ Do You Yahoo!? Get Yahoo!
