Hi zavid,

For your query I searched on and find the following link somewhat helpful to you. It is :
http://hydraulicslab.ucsd.edu/RS232/rs232.htm

I started my learning on RS232 in a book for 8051microcontroller by author majidi and majidi. It introduces about RS232 fundaments but not abt the types.

RS232 is an antique serial communications format used by the serial port. It has been replaced by USB.

I haven't used RS232 since 1975.

zavid-

Please constrain yourself to one thread per topic. As this is the second time I have had to delete a duplicate thread of yours, it is obvious you have not read the Posting Guidelines so I'm including the link for you.

If you violate the Posting Guidelines again, you will not be allowed to post on this site.

Thanks,

PS - If you have further questions on this topic, I would recommend asking the people here who have already shown you they have knowledge of the subject...

Hi weaknessforcats,

May be u havent used it since 1975. But for your information, I have worked on Microcontrollers and Embedded Systmes. And during that my experience in 2004-2006, I used this mean of communication for establishing Serial communication between Microcontroller 8051 and PC's com port.

So I am sure that it is still in use in market.RS422 and RS485 are the similar terms used in conjuction with this RS232.

Then you shouldn't have a problem.

RS232 is a specification for the pin assignments on the connector, in this case the serial port. What goes in and out of those data pins is device dependent. All you should need to do is ask the device for data and a byte shouot appear on the data pins.

In the case of Windows you do this with a serial port driver. Read this: http://msdn2.microsoft.com/en-us/library/ms923741.aspx.

Most likely you can use an existing driver. If not, then you will need to write one.

If you are looking to do research, Google is a better place to start. If you have trouble implementing code, then we're here to help. Please come back when you have a specific question about code, not when you want someone to do your work for you.
