NET OS 4.0 - PPP

All,I am trying to establish a PPP link over serial line. I was able to do this successfully. I had the following setting for the PPP connections (in windows) 1) Created a modem connection (as communication between two comps) 2) make it accepts incoming calls 3) Set range as Server IP address 10.2.2.1 Client IP Address 10.2.2.50 This set ups works perfectly, the Peer is assigned 10.2.2.1 and my card gets 10.2.2.2 and I can ping it. The problem comes when I set the Server IP address as 10.2.2.0 I see no communication at all. Anyone knows about this ? Also has anyone implemented a LCP_ECHO , to chek if the PPP link works ok ? Thanks for any input !!!

Anyone ???
