Detecting modem hangup with socjet

[Pattt]

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.
