Parameters

description
Specifies a message to be displayed in the Waiting for Call dialog box.

Return Value

ReturnCode value indicates success or error conditions.
Remarks
This method does not check to see whether a modem is actually connected to the serial port. It simply transmits the Hayes "AT" command to get the modem's attention, and then transmits the "ATS0=1" command to place the modem in answer mode. If the command fails for any reason, no error is returned. The procedure continues to the next statement only after the status box is dismissed (either because the modem established a connection, the user canceled, or the dialog box timed out).
