Thank you for sweeping up W9BU.
For my USB cable that I connect to my UV-5R Baofeng, I use the Prolific Driver version 188.8.131.52 dated 7/31/2007. The Windows driver won't get it done. The link Ermin provided above is where to go. On the actual port settings I think I left it at the default, but I use the following:
Bits per second - 57600
Data bits - 8
Parity - None
Stop bits - 1
Flow control - none
Pay attention to what port it uses, probably the same as you have now once you change the driver. Also I use CHIRP myself. That software is fantastic as it makes it easy to enter in freq's, or even import them using the software. You can easily import various repeaters as well and choose to skip over freq's when doing a scan.
Transceivers, filters and antennas. Having fun in the sun.
