Controlling RAS from a VC++ program in W95

Hello, we are working in a project in which we have to communicate
several PCs by means of telephone connections. One of them acts as
the
originator of the calls, the other ones wait for incoming calls. We
want
to use TCP/IP.
To do this we are using the dial-up networking facilities provided
by
Windows 95. The Remote Access Server provided with W95 locks the
COM
port so that it cannot be used by any other process (our program).
We
would like to be able to start and stop the RAS from our program
(telling it which of the modems installed in the PC it has to use).
We
think that there are functions of the RAS API that allow to do
this, but
they don't work in W95/98.
If it is not possible to control the start/stop of the RAS we would
like

to know about other ways of establishing TCP/IP connections between
two
PC's via a telephone connection from a VC++ program.

If you could help us we would be very grateful.
Thanks in advance.
