WaitForCall Function
Initializes the modem to automatically answer an incoming call and opens a status dialog box until a connection has been established.
object.WaitForCall() As ReturnCode

Return Value

ReturnCode value indicates success or error conditions.
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).
