B-1. Why can't my system detect BTC software modem?
1. There is no available IRQ in your system. Remove some devices.
  2. Resource Conflict. You can check your resource assignment in "System" in "Control Panel".
  3. Make sure to plug your internal modem card into your PC slot.
  4. PNP compatibility problem. Due to the imperfect ISA PNP protocol, some motherboards can not detect 56IP as a PNP modem. Please set the jumpers on the modem card to non-PNP mode and install your modem as a non-PNP one. To install a non-PNP modem, check out `How do I install non-PNP 56IP drivers in Windows95 and 98?`.
 
B-2 Where can I get BTC modem driver?
You can get the newest driver for your modem from BTC web site http://www.btc-corp.com/software/index.html
 
B-3 Can 56IPI run on NT Server 4.0?
Yes, 56IPI can be run on NT4.0 server. Software modems take a little more CPU resource than other kinds of modems. The CPU resource is valuable in NT Server 4.0 for a lot of service, such as: IIS web server, exchange server, SQL server so we wouldn't recommend users to use any kind of software modems in NT Server 4.0. However, if users still want to run 56IPI in NT Server, please install the driver with the setup.exe from the zip files from our web!
 
B-4 How do I install my modem driver?
Please refer to your manual in the bundled CD.
 
B-5 How do I update my modem driver?
1. Remove the old driver.
For PCtel software modem, please use "PCtel modem" utility in "Control Panel".
For RockWell modem, please use "modem" utility in "Control Panel".
  2. Uncompress the compressed file if you download the driver from our website.
  3. Restart your PC and your modem if your modem is an external one.
  4. When Windows finds your modem, enter into your new driver directory in "Install Wizard" to install the new driver for your modem.
 
B-6 How do I check if my driver is installed successfully?
Run `Modem` in the `Control Panel`. Click on the `Diagnostics tab`. Select your software modem HSP MicroModem 56 and click on `More Info` button to check the connection. Another dialog box will pop up if your driver is installed successfully.
 
 
 
B-7 Why can't my software modem work?
Follow the steps below to find out your problem:
  a. Check if your modem driver is installed successfully. If not, check these:
  • Does your PC find your modem?
    If not, check Why can't my system detect BTC software modem?

  • Check if there is resource conflict.

  • Mixed Driver
    The old driver is not removed completely before installing a new one. Remove the old driver from "HSP modem" in the "Control Panel". Make sure to check if these two files has been deleted:

    1. "Pcwave.inf" in the \Windows\inf
    2. "Pctel,inf mdmchipv.inf" in the \Windows\inf\other\

    Restart your PC and install the driver. If installed successfully, your software modem will be on COMX, X=3,4 or 5.

  • Resource Assignment Mismatch. Please enable the two items "Auto-Assign System resource" and "PnP OS support" in PnP/PCI BIOS setting to let your PC assign resource for you.

    For using VIA MVP3 system chip in Windows98, you must run the IRQ patch program, otherwise the system will not work. Please refer to your system manual for the type of your system chip.

    If your system still can not diagnose your modem after all these steps, please return your modem for servicing.
  b. Check if your telephone line is plugged well in the phone jack of the modem card and make sure your telephone line is OK.
  c. Use AT Command in `Hyper Terminal` to communicate with your modem. You will hear answering tone after you type the command "ATH1" in the `Hyper Terminal`. Type "ATH" to turn off the dialing tone. If you can not hear any dialing tone, have your modem for servicing.

If your modem passes all the checkings listed above and still your modem cannot work, it's time to check out your software application settings.
 
B-8 Why does the modem driver always install my modem in COM3 or COM4?
All the communication applications communicate with the modem through a serial port. They send commands and receive status codes to and from external modems through physical COM pot. Internal modems integrate the COM port on the card whereas the software modem driver simulates COM port to communicate with application programs. The COM port name is decided by the I/O address, like below:
 
Name I/O address
COM1 3F8
COM2 2F8
COM3 3E8
COM4 2E8
  Most PC's come with physical COM1 and COM2 so the software modem driver uses 3E8 or 2E8, which is why the software modems are always installed on COM3 or COM4.
 
B-9 How do I install non-PNP 56IP drivers in Windows95 and 98?
01. Power down your PC. Set the jumpers on 56IP card to non-PNP.
PNP   non-PNP
  02. Power on your PC. Windows will not find your 56IP. Use [Add Hardware] in the [Control Panel] to add a communication device for 56IP.
  03. Do not let windows add hardware for you. Choose "Select the hardware from the list".
  04. Select "Port" and install it from the "Have Disk".
   
   
  05. Type in the driver directory, ex: x:\driver\win95&98 (x is your CD-ROM drive). Choose "Pctel HSP Modem Communication Port".
  06. After successful installation, click the "Next" button of the hardware status report page. Do not restart your PC now! Use [system] in the [Control Panel] to change the resource for this communication port. If you choose `3E8` for your port, your port name will be COM3; `2E8` for COM4. Get an available IRQ for your port and set the DTE speed to 115200 bps.
  07. Use [modem] in the [Control Panel] to install 56IP on the port. Click "Add..." button on the "General" page to add the modem.
  08. Choose "Don't run the Hardware Installation Wizard" and do not let Windows auto-detect your modem. Install the driver from the directory, x:\win95&98\driver by clicking on the "Have Disk..." button.
  09. Choose "V.90 K56flex HSP modem" to install on the port you created.
   
   
  10. Restart your PC. And your 56IP is ready to use.
 
B-10 How do I install non-PNP K56I/K56IW drivers?
Firstly, you have to check the hardware settings.
  1. Set JP5 to non-PNP mode.
For JP1 to work with each proprietary COM port, set as follows:
   
COM JP1
1 2, 3, 4 capped
2 2, 5, 6 capped
3 1, 3, 4 capped
4 1, 5, 6 capped
    For JP1 to work with each proprietary IRQ, set as the table below for K56I & K56IW.
   
IRQ JP1
2 (9) 7 capped
3 5 capped
4 3 capped
5 8 capped
7 9 capped
    The table below applies to JP1 on K56IW
   
IRQ JP1
10 A capped
11 B capped
12 C capped
15 D capped
    *** The default is COM4, IRQ 9.
  2. Power on your PC. Windows will not find your 56IP. Use [Add Hardware] in the [Control Panel] to add a communication device for 56IP.
  3. Do not let windows add hardware for you. Choose "Select the hardware from the list".
  4. Select "Port". Select "Standard port types" and click "Next".
   
   
  5. After successful installation, click the "Next" button of the hardware status report page. Do not restart your PC now!

Make sure to set the resource correctly for your card to avoid conflict, which would result your system to hang up. And set the DTE speed to 115200 bps.
   
   
  6. After changing the COM port setting, Windows will restart itself.
  7. Use [modem] in the [Control Panel] to install K56I/K56IW on the port. Click "Add" button on the "General" page to add the modem.
  8. Choose "Don't run the Hardware Installation Wizard" and "Do not let Windows auto-detects your modem". And install the driver from the driver directory clicking "Have Disk..." button.
