See the following pages for detailed information regarding the command
structure to the probe. When the probe completes the command, it responds with
a string consisting of:

A start character (":")

The command letter

Data (if required)

<CR> (a carriage return)
If the command does not require the probe to return any data, the probe simply
responds with the start character (":") then the command letter and a carriage
return. If an error occurs, the probe responds with an error code.
