Many of the "next generation" laptops have the serial port being phased out because the manufacturers believe the consumer no longer has a need with USB products. There are two primary options if a serial port is not available; USB-to-serial or PCMCIA-to-serial. I would recommend the PCMCIA-to-serial, because the PCMCIA is essentially the PCI bus... I use this, and I have had sucess in connecting to AB, Omron, etc. PLCs. ALSO this option allows connection to DOS programs. See http://www.Quatech.com Best of luck....
