This README.TXT file contains information to help you set up your 3CXM356 WinModem and avoid common problem areas when using your PC Card. --------------------------------------------------------------- TABLE OF CONTENTS 1.

If You See References to DOS or Windows 3.1x On the Help Screens During Setup Ignore them. Your Winmodem supports only Windows 98, 95, or NT 4.0. --------------------------------------------------------------- 2. If You Have Problems Connecting Be sure the modem initialization string in your communications software contains AT&F for hardware flow control. ------------------------------------------------------------- 3. If You Do Not See a "Change Resources" Dialog Box During Setup Using Windows NT 4.0 In some cases, the "Change Resources" window may be covered by another window. If the "Change Resources" window does not appear before you are prompted to restart your computer, minimize the dominant window. When the "Change Resources" window appears, you may either: A. Keep the settings displayed in the dialog box by restarting your computer. B. Change some or all the settings displayed and restart. --------------------------------------------------------------- 4. If You are Using CardWizard for Windows NT 4.0 Because of existing limitations in CardWorks for NT, we recommend you do not use CardWizard with Windows NT 4.0. --------------------------------------------------------------- 5. If You are Using Quicken Version 6 The default maximum baud rate of a modem in Quicken 6 is 19,200bps. Follow the instructions in the Quicken 6 manual to increase this baud rate for your Winmodem. --------------------------------------------------------------- 6. If You are Connecting to a Comsphere 3820+ Modem When you're connecting to a Comsphere 3820+ modem at speeds of 4800bps or lower, you must disable the V.8 protocol in your modem. To do this, change S-Register 32 from the default 2 to 0. --------------------------------------------------------------- 7. If Your ISP is MindSpring version 3.02 or Higher (Windows 98) The latest version of MindSpring is not compatible with Windows 98 using the 3CXM356 or 3CCM356 Winmodem. We recommend you continue to use Windows 95 or switch to another ISP. --------------------------------------------------------------- 8. If Your Modem Won't Answer a Data Call Most communications software packages allow you to select one of the following ways to answer a call: "detect fax & data", "data only", "fax only", and "ignore ring". If you're using RapidComm software and have "detect fax & data" selected, if your modem won't answer data calls, set the answer mode to "data only". --------------------------------------------------------------- 9. If You Get a General Protection Fault You must be using Windows 98, Windows 95, or Windows NT. General protection faults (GPF) usually occur when insufficient memory is allocated by the computer to perform a task. If you get a general protection fault while using your modem, do one or more of the following: - Be sure your computer meets the minimum memory requirements for the modem: At least a 486 laptop At least a 50 Mhz processor At least 8 MB RAM (Windows NT requires 16) At least 10 MB of free hard disk space - Be sure your COM port or IRQ setting doesn't conflict with any other devices on your computer - Remove and reinsert the modem in the slot to be sure it's seated correctly and securely - Uninstall and reinstall your modem - Free up memory by closing open applications until no more GPFs appear. -------------------------------------------------------------- 10. Using ATYx Commands Because ATYx commands are not enabled for use with your Winmodem, the Set Next Reset feature is not available. --------------------------------------------------------------- 11. Using ATDT" Dial Strings We recommend you do not use letters with ATD dialing commands. --------------------------------------------------------------- 12. Faxing High Resolution Pages When faxing high resolution pages, the text received will be distorted if both the sending and the receiving modem do not use High Resolution Mode. ---------------------------------------------------------------Download Driver Pack
