My company does direct control of these ports for some of our imbedded control systems. Most of the code is in VB and of little use to a linux fellow such as yourself. These is a disturbing trend in cheap new computers to emulate the hardware in software. These is no actual UART to control. THis has made it necessary for us to test samples of new models as the clueless salesmen have no ieda what they are selling.
