hello guys,

I have a tricky problem. In my application, I need to send some data through
some certain serial ports, say COM7 and COM8. What I am trying to do, is to
add a modem (virtual modem) to system (WIN XP/2000), and try to dial this
modem, and send/receive data through the modem's serial ports. I searched
the web for several days and never found any source code, example or
tutorial for this topic. If anybody has idea for this, please give me some
hints.Thank you very very much.

Typically you use the COM port directly and not any "virtual modem". This
would be impossible to help you with without knowing exactly what you are
doing and how it is supposed to be done.
 
well, what I want is to dial up to an ISP through a modem on another
desktop.


Desktop A <--------------> Desktop B<------------>ISP
(Without modem) (with modem)
(My application)

Deskop A and B communicate through a serial port, say, COM 5(acutally I am
using bluetooth to connect them).

What I am trying to do is to create modem connection on A, and set its COM
port to COM 5. So when my application dials to ISP, the signal actually goes
through COM 5.

What I concern now, are:
1. how to write code to add a modem (with its serial port set to COM 5) to
desktop A, and
2. once the modem is ready, how to dial-up ISP in my application.

thanks,
Eric
