I place this message in the Internet section, altough it's not directly related to the Internet.
It's more about modem communications.

The problem is as follows.

PC1 and PC2 are separated by 800 km.

PC1 validates a form and attempts to send the data to PC2.
If PC2 is busy, try antoher 4 times
IF data transfer succeeded, PC2 sends an acknoldgement to PC1.

On PC2 side, PC2 is always listening. If there's a call, modem attends the call,
receives the data, sends an acknowledgment and disconnects.

I am being asked if I could do that in VFP, and hell, I don't have a clear idea where to start from...
