RE: Wiz550io 동작 관련 두번째 질문 입니다

LOOPBACK connect 함수에서 TIMEOUT으로 빠져 나오거든여.
IP는 ping test로 동작 하는것 확인 했구여.
무엇이 문제 일까여.
=> ping test가 정상동작인 것으로 보아 Connect시 ARP Time-out에 의해 Time-out이 발생하는 것 갖지는 않습니다.
PC쪽에 서버의 Port number혹은
방화벽쪽을 살펴보시기 바랍니다.
감사합니다.

Wiz550io와 노트북과 1:1 통신을 하고 있거든여.
방화벽 문제는 아닌거 같네여.
노트북과 데스크탑으로 hercules로 TCP 동작을 하면 정상 동작 합니다.
프로그램은 다음과 같습니다.
while(1)
{
loopback_tcpc(4, 5000);
}
