I have a device which can communicate with PC. When I connect it to PC it forms a vitual com port, it has Silabs IC in it . Then I send 'A' from termianl & it responds back with ack.

Now instead of reading it from PC, I want to read it with help of my host microcontroller card.
How to do that. I can run UART interface. Should I put another UBS-uart converter in between.
But device form virtual com port. If I connect my host controller what should I do initially.
