Thanks Koepel for your time. I have similar convertor, so I might try this solution. Any sugestion as to what terminal program I should use. Is TeraTerm-5 a good candidate?
If I use my Arduino Micro for this, will the Rx and Tx be addressed with the "serial"-commands? And will the IDE still be available for other communications. Sorry, for this kind of silly questions. I definitely need a push in the right directions.
