A typical PC program that is used widely for logging and troubleshooting NMEA 0183 data is:

Explanation
NMEA 0183 is a standard for communicating with marine electronic devices, often used in amateur radio for GPS data or other position reporting. It typically uses an RS-232 serial connection and transmits plain text sentences. **HyperTerminal** (or similar terminal emulator programs) is designed to connect to serial ports and display the incoming text data in real-time. This functionality is crucial for logging, monitoring, and troubleshooting NMEA 0183 streams, as you can see the raw sentences being transmitted, check their format, and identify any issues. **Excel**, a spreadsheet program, **Windows Explorer**, a file manager, and **Microsoft Word**, a word processor, are not designed to interface directly with serial ports to capture and display live data streams. While data might eventually be imported into Excel, these programs lack the fundamental serial communication capabilities required for real-time logging and troubleshooting of protocols like NMEA 0183.
