It is impossible to share a Port com on the same computer. But when you use the freeware ”Virtual Serial Port Emulator” you can:

Make a simulation Master/Slave on the same computer

Unlike regular serial port, the software provide a virtual device that can be opened twice.  You can use the same virtual port com to exchange data between separate applications.

Share a physical Port com between several applications

Let’s assume that you have GPS receiver that’s already connected to your computer to the physical serial port COM1. You can create a virtual device that represents an existing serial port to share it between different applications.

Solution

Make a simulation client/server on the same computer

1. Close program that opened serial port.
2.  Run VSPE and create the connector device.
   
3. Select COM3 in “Virtual serial port” combo box.
   
   
4.  Now two different application can communicate on COM3.
   
   

Share a physical Port com between several applications:

1.  Close program that opened serial port.
2.  Run VSPE and create the splitter device.
   
3. Select COM1 in “Data source serial port” combo box and COM3 in “Virtual serial port”.
   
   
4.  Now configure all your programs to receive data from COM3.
   
   

Other information:

• You can use TCP/IP connection to remote computer and transfers data from existing serial port to remote PC and vice versa.
• The software is not freeware for 64 bit platform.
  
• You can download the Virtual Serial Port Emulator from eterlogic.com.
