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 Client IP Address This set ups works perfectly, the Peer is assigned and my card gets and I can ping it. The problem comes when I set the Server IP address as 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 ???
