* Function name: init_IO
* Parameters: none
* Return value: none
* Description: This routine initializes the SICL environment. It sets up
* error handling, opens both an interface and device session, sets timeout
* values, clears the interface by pulsing IFC, and clears the instrument
* by performing a Selected Device Clear.

* Function name: write_IO
* Parameters: char *buffer which is a pointer to the character string to be
* output; unsigned long length which is the length of the string to be output
* Return value: none
* Description: This routine outputs strings to the scope device session
* using the unformatted I/O SICL commands.
