    HP Omnibook Xe3 GF USB to Serial Port


    by dcook ·

    Has anyone had a problem and a solution in using the HP Omnibook Xe3 Laptop USB to Serial dongle. Under Win98 SE it creates a virtual COM1 port in place of the hardware serial port used on the GC series notebooks. My problem is that it works fine with an external modem and my digital camera but not to connect to a PLC allowing programming, setup and manipulation of building automation control systems.

Please help. HP says “?”.
