PPP Compression problem
 

I had installed OpenLinux Caldera 3.1, on my computer (PII 266Mhz 64MB) and tried to connect to the Internet.
I used the inbuilt wizard to configure my ISP. The wizard correctly identified my modem (US Robotics Sportster 33.6 fax modem, connected on COM2 i.e. /dev/ttyS1) and also dialled my ISP's number. The problem came after that, it gave a
PPP Demon Died (PPP Negotiation Failed) error.
The following are the contents of the KSaferPPP's log :
