A dial-up dialer for connection to Internet providers

Sample Image - afdialer.jpg


I have written dial-up dialer for connection to Internet providers. This is a simple little program that dials your modem and tracks your online time. It also allows the user to setup multiple dial in numbers and gives the user a basic settings screen.

The sourcecode is freeware and can be distributed under terms of GPL. It is written in Visual C++ with use of MFC, RAS API and several other APIs like Performance Counters and multimedia API. Contact me if you have any suggestions on this software ( or on this article (

Well, I've figured uit how to do it the 'easy' way and I've implemented it as well. It works pretty nicely. Here's what I did:
I took the MSComm ActiveX object and put it in my project. Looking at the functionality I wasn't happy yet, so I built my own wrapper around it.
Next I made connection via the modem by sending simple AT-commands throught the MSComm object to the COM ports like 'ATDT37' for calling the telephone number 37. I did have some problems using the ISDN modems, but found that using 'ATB20DT37' solved these problems...
Both my client and server application use the MSComm, topped off with a synchronous communication protocol I wrote myself. The system is now operational, sending thousands of files to about 20 clients throughout the country.
Thanks for your input, though!
Structured programming vs. chaotic mind boggling
