Do I need to use specific 'PCI to serial port card' presented on your web site for my xpc target computer?

I built my simulink model for RS-232 communication with external PC using FIFO blocks. But, when I read the help document and tried several ways, it looks like separate ports are needed for each of sending and receiving data. Using both sending and receiving blocks at the same time with port 1 showed me an error. Is it correct to use different com ports for sending and receiving data?

Now, I am trying to add extra com port using "PCI to RS-232 card". In this case, do I need to use the hardware presented on your web site? If so, can you give the direction about how to install drivers for my device on xpc target?

Thanks.

You can send and receive with the same port. See http://www.mathworks.com/help/instrument/building-simulink-models-to-send-and-receive-data.html

Actually, I am using FIFO blocks in XPC library. I know usually it's possible to do bi-directional communication with RS-232. But, when I tried that with the blocks, I got the error saying "Error evaluating 'InitFcn' callback of Baseboard RS232 Send Receive block (mask) 'Baseboard Serial F1'. This block shares a UART address with another serial IO block. This won't work."

You can do both; see http://www.mathworks.com/matlabcentral/newsreader/view_thread/162502

Thank you Walter. It works now.
