Simulating PIC and Serial Port Communication in Proteus

I'm using Proteus to simulate a simple communication between PIC16F877A and a Serial Port.

I Installed VSPE, I created 2 Virtual Ports COM2 and COM3, I picked "pair" in VSPE so that COM2 and COM3 are connected together.

In Proteus I added the PIC and the COMPIM, I edited the properties of COMPIM so that it works as COM2, all other properties I kept them the same (Baud,etc..).

I added a Virtual Terminal to read the incoming and outgoing data.



I created a small application in C#, when I try to send some data to COM3, the data shows perfectly on the Virtual Terminal connected to COM2.

But when I send bytes from the PIC to COM2 (In Proteus), the Virtual Terminal displays weird characters (Mostly "?"), and in C# I get weird Numbers.



The PIC code is the following:


I'm simply trying to send number 10, what am I missing here?

Zip and post your project files and Proteus file. Maybe baudrate is not matching or data is inverted. Remove COMPIM and just connect Tx pin of MCU to RXD pin of Virtual Terminal and see if it displays characters properly. If not, then problem is in code or baudrate or invert.
