serial port

hi - is there a simple and good way to control the 9-pin serial port at the back of your computer? i would like to use it for some simple electronics commands and i need to be able to send a certain number of pules to it over a set time,- also how can you recieve? i found this link on google, is it right? and what is i don't want to send a message to want to pulse it? any ideas? :) cheers, surgeproof ------------------------------------------------------- ithium is the best.

Simple? Not on your life... You said your looking to send signal pulses? The article you found won't let you do that. That article deals with properly formatted serial communications. You're apparently looking at manipulating the serial port hardware directly and in very non-standard methods. Your going to have a DIFFICULT time with this one. Receiving data is going to be very difficult at best. You might have better luck with using the parallel port for a project like this. Most of the same problems apply, but there is more documentation on this port than with serial.

I agree with Dave, what you're trying to do is pretty impossible. Better to get hold of a development kit for a simple microcontroller (e.g. a Arizona Micro PIC device) that has an on-baord UART and talk to that via your PC serial port. The PIC can be programmed to generate your pulses, etc, depending on the instructions it gets via the serial port.

cheers both for your helpful responses. i will soon be getting more into PIC development, and i have a PIC programmer coming soon, so i may be able to figure out UART if i need it. :) thanks for now, surgeproof. ------------------------------------------------------- ithium is the best.
