HP4070 Prober Communication Code Example: Opening a Connection and Sending a Command

The given code is using the HP4070 prober library to communicate with a prober device. The code opens a connection to the prober device, sends a command to the device, and then closes the connection. \n\nHere's a breakdown of the code:\n\n- The header files stdio.h, errno.h, prober.h, and sicl.h are included.\n- The constant PADDRES is defined as the address of the prober device. It can be either the physical address (e.g., "25,5") or the logical address (e.g., "hpib7").\n- The function pcopen is defined but not used in the main function.\n- In the main function, the pcopen function is called.\n- The pcopen function initializes some variables and sets the error handling mode to exit on error.\n- The function opens a connection to the prober device using the iopen function.\n- The timeout for the communication is set to 0 using the itimeout function.\n- The function sends the command "L\r\n" to the prober device using the iprintf function.\n- Finally, the connection to the prober device is closed using the iclose function.\n\nNote: The code is missing error handling, so it may not handle errors properly.
