           Summary: cyg_ppp_up and cyg_wait_up sometimes never return
           Product: eCos
           Version: 3.0
          Platform: All
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: critical
          Priority: low
         Component: TCP/IP
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: kenkyee@excite.com
                CC: ecos-bugs@ecos.sourceware.org
             Class: Advice Request


Our application requires that we make multiple PPP connections to minimize
connection costs, so we have a pretty simple core bit of code that brings the
PPP line up and down.
Sometimes, eCos will hang during the cyg_ppp_up or cyg_ppp_wait_up calls.  The
only thing that shows up in the diag console is:
SYSLOG 08: Using interface ppp0
SYSLOG 04: Connect: ppp0 <--> /dev/ser0
SYSLOG 08: Connect time expired
SYSLOG 04: Connection terminated, connected for 1 minutes

The core loop is roughly like this:
    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) {
                int pppTimeout = PPPMAXUPTIMESECS;    // PPP timeout in seconds
                while ((pppTimeout-- > 0) && (cyg_ppp_wait_up(pppHandle) == 0))
{
                    Thread::sleep(sec(1));
                }
            cyg_ppp_down(pppHandle);
        }
    }
