hi! i am working on a college project where i need to send sms through pc having VB+ GUI. will be using nxp 2144 or 2146 arm microcontroller and wavecom 2686 gsm module...to start with how do i interface the microcontroller to pc....i mean i might have to consider of a hardware design for the board...pls help me how do i go abt it....sending sms is not the sole purpose, voice interface will be added once sending sms part is accomplished
If the decisions to send an SMS is made by a PC, I would either use a USB-connected GSM modem (good for a vehicle-mounted PC) or subscribe to an Internet-based SMS service.
Microcontrollers are fun, but have to add some value to the solution. If they don't, then there is no need for them.
-> they have given a diagram that is to be used to interface the microcontroller through the USB. <-

I think that, it is for circuit design, right?
What do you mean by "how should i implement it."?
