How to send a zip file using MSCOMM

[makdu]

Hi all,
Using Modem and MSCOMM, I dialed a computer from another computer. I am able to send some text messages. Also i read from a text file and has send the data to the another computer, where it is collected to a text file.
My problem is, I want to send a file, like zip file from one computer and receive it in another computer with same name ,through MSCOMM and MODEM. What should be the starting point for this ?

I have a server computer and 5 other client computers. I dial each computer using my VB application to send and receive files/data. It works fine with 3 of the client computer and other 2 , i am not able to get it connected. This two computer are connected to a fax line . So when ever i try to dial this two computer from server computer, the exchange detect it as not a fax data and drops the line. I Want to bypass this problem. Is there a way
