cannot connect linux using 56kflex modem with ppp2.2

Post by kenny pan » Thu, 08 Jan 1998 04:00:00



I am not able to connect my linux box to my isp 56kflex line since I
upgrade my 28.8 to 56kflex modem. However it can still link up to 28.8
line. Attached is the extract of debug information. Can anybody give me
a hand? I am sure my isp is using the k56flex standard. Besides there is
no any problem to connect with the same 56kflex line with the same modem
using win95 or nt. Therefore I am sure that the hardware is not the
source of the problem. My ppp version is ppp2.2 and my linux kernel
version is 2.0.30.

thanks in advance
