Changes in Host Application to use  Windows USB to Serial driver implemented COM port

Question: Does the USB to Serial driver create a real COMx Port? Are there any changes to be done in the current host application code that uses the RS-232 port to be able to use the implemented COMx Port?



The driver creates a virtual COM port. There should be no changes to the your host application, and on the peripheral side you only need to add our chip as the input to the old RS-232 serial port.  Existing host applications do need to be flexible enough to allow selection of any COM: port (they can't be hard coded to use the hardware ports COM1: or COM2:).
