hey 
how to make an arduino code for a (usb/virtual comm) Rs232 communication in the Arduino Ide?
thanks
I don't understand what you want help with. You need to provide more information.
If you are trying to connect some device that uses RS232 voltage levels to an Arduino then you will need something like a MAX232 to convert the RS232 voltage levels to the Arduino's TTL voltage levels. RS232 voltage levels can damage an Arduino.

sry, i mean.. i have to make a serial communikation (rs232 ) between a computer and the arduino ide (seriell monitor), i got this task from my teacher idk what to do

Does the PC have a RS232 port?
.
i think so, he exactly wrote: the connection should be via Rs232 in the Arduino Ide

He needs to clarify, because I have no idea what he wants.

Perhaps you teacher just means to make a serial connection to the IDE. RS-232 cannot be done because the IDE uses the USB connection. Writing a program to send and receive from the IDE serial monitor would be a good first exercise.

Hi,
Can you post the exact task that you teacher has set you?
You must have a note or paper from the teacher saying what he/she wants you to do.
Thanks.. Tom..
I bet the task the teacher asked is something like: Program UART to make what does Serial with the PC

This makes no sense because the Arduino Serial Monitor is a program running on the computer and there is no need for serial communication between the the computer and the Serial Monitor.
My guess is that you were not listening when the teacher gave out the assignment. If so you need to ask your teacher to explain it again.

I would like to take the meaning of the statement as follows and then proceed with a suggestion:
1. The Arduino UNO will remain connected with his PC (PC1) via UART (hradware) Port/USB Port of the UNO. In the PC, a Serial Monitor will appear by virtue of the UNO's IDE.
2. Another PC (PC2) will communicate with the Serial Monitor of PC1. The communication linK is: RS232 Port of PC2, MAX232 Chip (RS232 < ----> TTL Conversion), Software UART Port of UNO, Hardware UART Port of UNO, USB Port of UNO, and the Serial Monitor.
4. Now-a-days, it is hard to find PC that is equipped with RS232 Port; the possible connection layout would be as follows:
USB Port of PC2, USB-to-RS232 Converter Cable, MAX232 Chip (RS232 < ----> TTL Conversion), Software UART Port of UNO, Hardware UART Port of UNO, USB Port of UNO, and the Serial Monitor.
On the basis of above, I would suggest the following lay out (too complicated for a beginner!):

That is all very complicated and may have not relation to the OP's need. In my experience people who ask poor questions rarely have complex problems.
IMHO it makes more sense to wait for more info from the OP.

I guess English is not your main language?
Take the task your teacher gave you type it into Google Translate https://translate.google.com/
and post in English exactly what you have been asked to do.
