I got the output below from my program. Not the SIGTRAP. I have no
idea what that is.

Here's the mean code that doesn't like me. It only happens when I do an
accept. OpenListenSocket () opens the socket with socket () and bind
(). Then when accept is called it gets this SIGTRAP. What is a
SIGTRAP? I assume I made a booboo somewhere!?
void CommandThread (cyg_addrword_t data)
{
int commandListenSocket,
commandSocket;
struct sockaddr_in addr;
if (!OpenListenSocket (&commandSocket, COMMANDPORT_NUM))
return;
while (1)
{
diag_printf ("Command Thread!\n");
accept (commandListenSocket, &addr, sizeof (addr));
cyg_thread_delay (100); // one second
}
}
