Alright, so I've purchased two identical 56k modems and have them attached and connected to my two development machines.

My first objective is to simply get data transfer operating. I initialize the modems and place one in accepting/answering state and attempt to connect the other and receive the error "NO DIAL TONE" from the latter.

How do I generate a dial-tone? Is it even possible with these consumer modems? Or am I missing the point?

The environment I'm working in is Windows using the usual file API. My reference material for the modem is the manual from the manufacturer along with the INF files included with the driver (it's a USB modem)

Thanks,

Matt.
