Sorry...this should also have included cyg_ppp_up(). That sometimes never
returns as well..symptom is the same as with cyg_ppp_wait_up()....
The core ppp loop is fairly trivial, but it does bring the connection up/down a
lot to minimize connection time costs:
cyg_ppp_handle_t pppHandle = cyg_ppp_up(PPP_PORT, &options);
if (pppHandle != 0) {
int pppStatus = cyg_ppp_wait_up(pppHandle);
if (pppStatus == 0) {
// wait for connection to come down
if (cyg_ppp_wait_up(pppHandle) == 0) {
while ((pppTimeout-- > 0) && (cyg_ppp_wait_up(pppHandle) == 0))
{
Thread::sleep(sec(1));
}
cyg_ppp_down(pppHandle);
}
}
}
