Any one have network connection via dialup modem and PPP?
==================================================================================
I am trying to connect network by CDMA modem by PPP protocol vis a serial port.
I have sucess on dialing the modem and getting connection messages but thereafter
I am not able to login and to connect network(ppp).
I think that -U and -T option is not work. Anyone have these experience?
Please comment.
Followings are test results.
