If the barcode reader connects to the computers 9pin RS232 port (serial port or COM port), I would reccomend using the new 2.0 class System.IO.Ports.SerialPort. I think the limit for serial ports is 256 (why 256 well that is the number of distinct values a byte can have and as we all know serial ports have been around for a long long time.)
