SYMPTOMS
In Windows NT, the Cardfile can be used to store phone numbers and Auto- dial by using the F5 key. However, this may not work with all modems. The same modem may work with the Terminal program but may not work with the Cardfile Autodial feature.



CAUSE
Some modems must have DTR (Data Terminal Ready) set high before they will dial or accept commands from the computer. Cardfile does not raise DTR.



RESOLUTION
Force DTR to always be high on the modem. There may be different ways to do this on different modems. Some modems are configurable with dip switch settings while others can be configured with savable AT commands. Please see your modem documentation for the proper procedure.



Steps to Reproduce Problem
Assume the phone numbers are already stored in Cardfile.

NOTE: You need a Hayes or Hayes-compatible modem to dial a number on a card.


 * 1) Select the card that contains the number you want to dial.
 * 2) From the Card menu, choose Autodial. In the Number box, Cardfile displays the first number it finds.
 * 3) Type a new number, if necessary.
 * 4) To use a prefix with the number in the Number box, select the Use Prefix check box. Change the prefix, if necessary.
 * 5) To set up the modem, choose the Setup button, and then select the appropriate modem options.
 * 6) Choose the OK button.

Modem may not dial.
