MSComm

[Phil Thurmon]

I think I need to send or receive a signel to get a connetion to the computer I am dialing but I am not sure how to do it. I have looked at the program From MSDN but still do not undestand why theres will display data recived and mine will not. I can call my internet provider with their program and it will com back with username then it will start to send data. all mine does is display OK then the other computer will hangup.Here is my code
// DIAL_OUT.cpp : implementation file

#include "stdafx.h"
#include "Acculeve.h"
#include "DIAL_OUT.h"
