Modem data sending

Hi all.

I've found CTapiConnection and CTapiLine. Oddly enough, the CTapiConnection won't compile, but that isn't the real problem.

Both of these are good for opening a modem and dialing up a number. It seems, however, that this is for making a voice connection. I don't want to make a voice connection, I want a data connection (which I think I can set up with the LINECALLPARAMS Bearer Mode of LINEBEARERMODE_DATA).

Should that be the case, great. What I can't seem to discover is how to go about sending data down that line. I've looked for a Send or Write or something. Maybe I've overlooked it, but could anyone offer any suggestions?

Thanks
