I am creating a program that will act like a veriphone terminal (similar to a credit card terminal). Once connected(using a modem), the server sends me an ENQ (enquiry) Then I am supposed to send a formatted string.Then it sends me a formatted string, and I send an ACK. Simple? If I knew how to use the Comm control. I can't seem to get the on comm event to recieve the data. Does anyone have an example, know of a book, or online tutorial that will help understand how to use this control? Point me in the right direction?

Thanks
