[Rxtx] Virtual-Serial-Port and RXTX

[Glenn Davidson]

Michael,

I forgot to reply when I discovered why RXTX did not work with our Atmel USB Virtual Serial 
Port. It was finally determined that our device firmware had a bug that prevented RxTx from 
opening the virtual comm port. Once this bug was fixed, there have been no problems.

Initially testing was done using TeraTerm and the terminal emulator was able to connect 
inspite of the firmware defect. I don't recommend ever using TeraTerm for testing virtual 
comm ports!
