    These documents are provided electronically for the express purpose of assisting design engineers, software developers, and end-users with frequently asked questions about Rockwell products. Rockwell does not manufacture modems, just the chipsets that go into many modems. For specifics about particular hardware/software, it is often best to consult the actual modem manufacturer directly. Hardcopy versions of these and other documents can be obtained by contacting your local sales office. For a list of worldwide sales offices click here.

    Generic Modem User's Guides

    Generic Modems User's Guides are available in HTML format. Although most modems will NOT have all of the features described in a User Guide, the guides offer typical information for the generic modem design that Rockwell offers to modem manufacturers. Modem manufacturers often make significant changes or custom designs using Rockwell chips, so the information may be incorrect for your specific modem.

    Jumper / DIP switch settings

    Since Rockwell does not make the complete modem hardware (board) -- just the chipset -- Rockwell does not have any information about Jumper or DIP switch settings.
    If you don't have documentation on jumper or DIP switch settings, the best you can do is experiment and then examine the results with PortInfo (http://www.comminfo.com). Some detailed instructions are here.

    Some typical COMM port settings:

    Port# IRQ I/0 address
    COM1 4 3F8 hex
    COM2 3 2F8 hex
    COM3 4 3E8 hex *
    COM4 3 2E8 hex *
    * = de facto standards
