When the USB device's driver is implemented as a virtual com port it can be used as a normal comport
this means that hyperterminal is able to send/receive data to/from the usb2rs232 device (And yes, i've used hyperterminal to do that)
Hi,
Each usb-rs232 ic converter has its own drivers. There is no "generic" driver for this. One example of such chip is PL2303 (www.prolific.com.tw) . Another is FT232BM (www.ftdichip.com). Each chip has its own set of drivers for diff. versions of windows as well as for other os (linux, mac). Manufacturers of cable adapters usb-rs232 have to supply a media with drivers. As far as I know, most manufacturers use pl2303 from prolific. It is widespread.
Maybe there are some ..let's say dumb drivers which install a fake com port in your os. But if you want to interface a rs232 device over the USB bus, you will need an adapter and apropriate drivers.
