TCPnet: switching between PPP and Ethernet at runtime

Eric Severson

Hello,

I have a couple questions regarding TCPnet that I would appreciate some assistance on:

1) I am using raw TCP/IP sockets and at runtime I need to be able to dictate which communication platform the sockets open on (Ethernet vs PPP). Is it possible to do this?

2) For some reason I am not getting any DNS servers assigned through my PPP connection. My PPP device is a GPRS modem. Is there a setting that I need to enable to make this happen?

I have been reading the product manual and cannot seem to find the answers in there -- however, if they are there and I just missed them, please feel free to point me to the correct sections. Any insight would be greatly appreciated!

Thank you,
Eric

    Moreover, pay 10000$ for a uncomplete stack seems strange to me....
    TCPnet is pretty simple to play with , but you see quickly weaknesses of the stack:
    - it misses compatible berkeley sockets
    - waiting acks for each tcp packet is a real pain for data exchange with high ping .

    We're also considering to use, soon , lwip.
    But the weak in this case is the poor documentation :-/
