[WriteLog] USB to Serial Converter

[Joe Young]

Hello, I have seen some reference to this on here before. I will be 
upgrading to a
new computer soon and it only has one serial port. My existing computer has two
serial ports which I use for :

Com 1		Radio control
Com 2		TU

Any recommendations for a converter to access my TU with the new computer 
(USB to serial converter)?
Also, do these units come with some type of software? When I use WriteLog 
to assign Com 2
to my TU how will it know where to go on the USB to find the old Com 2? 
Another "first time"
user questions. Thanks and 73 de Joe, W6RLL.
