Dialing from the controller's keypad

If your controller is hooked up to a modem, a phone number may be dialed from the controller's keypad. This explanation is based on a sample application that is installed on your hard disk together with VisiLogic. To open this application, open the Help menu, click Examples, and then select Dialing via Vision Keypad.

About the Application

When downloaded, this application:

Displays a blinking cursor on-screen. This aids the user in entering a phone number by pressing keys on the Vision keypad.
'Converts' the entered numbers to ASCII, then saves them, as they are entered, into a vector of registers that starts at MI 1011, the Phone Entry vector. One ASCII character is entered into the low byte of each register.
A Transpose function is linked to the vector starting at MI1011. Transpose copies the low byte of each register in that vector, and stores it into the consecutive bytes of a vector that starts at MI 1001, the Phone Number Vector. For example, Transpose can extract the low bytes from MI 1011,1012, 1013 & 1013 and store all 4 bytes into MI 1001 and 1002.
Displays the numbers as they are entered, via the HMI variable Display ASCII String, which displays the Phone Number vector starting at MI 1001.
The character Carriage Return (ASCII value 13) is required by the modem as the final character in the number to be dialed. When the user has finished entering the number and presses Enter, the Carriage Return value is stored as the final character in the vector that provides the phone number.
Finally, the number us dialed via a Dial FB. The FB dials the number contained in the vector of registers starting with MI 1001, Phone Number vector.
