The PL2303TA USB to Serial Bridge Controller driver has been added on the top of this article. The PL2303TA allows for the connecting of the RS232 full duplex serial device to a USB device. What does this allow? Well it allows any program that was designed to use the COM port to now use the USB port. This means no new USB software needs to be used. With the adpater it now allows for taking advantage of the bulk transfer mode of the USB port as well as the automatic flow control.

The PL2303TA is faster than the UART ports. The baud rates are higher and there is no signal required. The rate generator also allows for 75 bps and 6 Mbps of transfer rates. The uses for this adapter is mainly for embedded devices or mobile devices. It has low power consumption which makes it very useful for remote sites.
