Chapter 8. Using Serial Commands

Introduction to Serial Commands

Serial commands allow you to communicate directly with the
receiver in machine language. Serial commands can be used
for various purposes such as:
• Changing default settings
• Monitoring different receiver statuses (internal operation,
constellations, etc.)
• Outputting messages on request
Serial commands fall into two categories:
• Set commands ($PASHS,...), used to set or modify the
receiver's internal parameters.
• Query commands ($PASHQ,...), used to interrogate the
receiver.
The few conventions used to describe the serial commands in
this manual are summarized in the table below.
