Not all of them support the RS-232 control lines, and a lot of applications require them. Serial ports are still widely used by control equipment. (Building lighting controllers, PLCs alarm controls, etc.) I picked up an Itronix T5200 for these applications, because it can survive abuse better then a laptop. (It is even extremely water resistant - 3" rain/hour.) Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
