When you use a USB to serial convertor, there appears on the PC a virtual serial port which behaves exactly like a normal serial port. Like COM5. Once this does, you can send data from PC to MCU or MCU to PC, both ways. So your serial to USB and USB to serial is one and the same thing.

Hi

usb to serial will work both ways
Check this link
**broken link removed**
under USB to RS-232 and RS-485 you can find a lot of information
