> The actual write and read of data does not work

Not a helpful description :-) ... you'll need to show us your code that does not work, ideally in a SSCCE, along with a description of what you are trying to achieve.

For some sample PM code that uses Win32::SerialPort see: How to read serial port with WIN32:SerialPort?
