can any one put me on the start of using serial port?
i need to know the pins and protocols to use serial port, i know alittle information
and how we configure it by using c programming language and visual c++.if there is asite to learn me using serial port from A to Z. and giving some applications.
and how we make IR remote control circuit that transmit and receive more than two signals.
can we use serial port to do that.
thank you for every body.

ok if we have a dc motor how to use remote control to revese its motion using two signals
Connect Signal1 to one terminal and Signal2 to the second terminal.
If Signal1 is 0V and Signal2 is 5V, dc motor rotates in one direction. If Signal1 is 5V and Signal2 is 0V, dc motor rotates in the reverse direction.
If Signal1 is 0V and Signal2 is 5V, dc motor rotates in one direction. If Signal1 is 5V and Signal2 is 0V, dc motor rotates in the reverse direction.

You need a receiver IC and modulate the IR signal at what the receiver is set to detect, usually between 32 and 40 kHz for remote control. You'd then need a way of decoding two data signals.

can you give me an application circuit that demonstrates the concept using TX and RX ir based circuit
I can give you loads of links regarding the theory and its various applications. But if you'll narrow down the topic to exactly how (i.e. using what) do you want to accomplish multi-signal transmission using IR, then it will be easier for both of us.
