int hello_main(int argc, char *argv[])
{
uint32_t i;
for(i = 0; i < 65536; i++)
{
printf("Hello, World!!\n");
}
printf("press any key!!\n");
if (getchar()=='t')
return 0;
else
return 1;
}
When ran in a Telnet session, the "press any key" is not displayed because the tcp session closed unexpectedly with:
tcp_input: ERROR: conn->sndseq xx, conn->unacked xx"
This is fixed by increasing the width of conn->sent to 32-bits to prevent overflow.
