Template Procedures
CheckForPrevInstance	Checks if Application is already running, and if so, activates it and brings it to the foreground.
DialNumber	Dials a Phone Number and Connects to a Remote System.
ComGetsTimeOut	Similar to ComGets in that it allows you to retrieve a string of characters up a specified Terminator. However it differs in that it stores the Terminator in the string, returns after a specified period of time, and optionally monitors Carrier Detect.
EncryptBuf	Encrypts or Decrypts a String Buffer.
GetOpenSaveFile	Prompts the user for a file to Open or Save As. In 32 bit Windows, it uses the Enhanced File Open and File Save As Dialog Boxes, which allows for using Long File Names in older versions of Clarion.
InitializePort	Automatically initializes the Serial Port to the correct Baud Rate, Parity, Data Bits and Stop Bits. In addition, it initializes the attached Modem.
ModemInstalled	Checks the Clear To Send (CTS) signal to determine if a Modem or other Device is attached and powered on.
PhoneMonitor	Monitors the Serial Port and Answers the Phone when it Rings.
WaitForString	Monitors the Serial Port for a specified String of Characters. Can be used to automate access to remote systems.
WaitForQueString	Monitors the Serial Port for Multiple Strings.
WaitForStringCapture	Monitors the Serial Port for a specified String of Characters. Writes all received characters to the Capture File.
