All,

I'm currently programming a socket client library.
I want to access a server via ppp

I can detect when the server close the socket

I wan to detect when the modem is switch to off and I can NOT.

Here is my code

lRet = select(uiSocket + 1, &fdsRead, NULL, NULL, &timeout);
switch (lRet)
{
  case SOCKET_ERROR:
    // Pbm with cnx
    break;

  case 0:
    // Timeout reached, nothing to read
    break;

  default:
     if (FD_ISSET(uiSocket, &fdsRead))
    {
      lLen = recv(uiSocket, ptrChar2Get, 1, 0);
      if (lLen <= 0)
      {
          // Pbm with cnx
      }

    // everything is fine
 }
}

Any idea?

Patrick.
