I configured a ppp connection using linuxconf for connecting to the IBM/ATT Global Network Internet service provider (www.ibm.net). The chat script it generates has the line: "CONNECT" "". This causes a carriage return to be sent to the ISP which prevents PPP from working with this particular ISP. If I delete the trailing "" or replace it with "\c" the connection comes up just fine. It would be nice if there was an option on linuxconf to suppress the carriage return after a connect.
If we added a separate checkbox option to linuxconf's chat script generation for every possible brokenness from every possible provider, we would have too many checkboxes to navigate... Instead, we're working on a more general solution that we hope will work for more people without clicking any checkboxes at all.
