In my work place there is a usb to serial multiport connected to a PC which controls servo motors ect. The 8 port(rs232) multiport is connected to the PC via a USB cable. My question is: Can these ports controlled at the same time from the PC or one port at a time? If for instance I have data transfer to COMport1 can I establish data transfer to COMport2 at the same time?
Here is a device similar I'm talking about: http://www.sunix.com.tw/itpd.php?cid=2&kid=4&gid=10&pid=764
