[OT] Programming the Serial (COM) port?

[Psionicist]

Hello there fellows!

In a language of your choice, preferable something basic or C/C++ (asm is also okay if you provide ALL code so i just have to compile it... heh), how do you send a high binary (number 1) to a specific pin on a com port?

That is, I want to send either a 1 or a 0 to say pin 5, how would I do that?

Thanks!

Edit: It's a standard RS232 interface

Sending and recieving information is actually incredible easy in eg Visual Basic using the MSCOMM control (http://v014u23han.net.maximumasp.com/show/21/). However you have to use other methods to just send data to one specific pin which is a little tricky. YOu cannot do this in visual basic but in qbasic, c/c++ and assembly.
