Reading The Received Data Fields
from the mobile station on the reverse control channel or reverse voice channel or
the raw data message bits displayed when a decoding error occurs, the control
program queries one, some, or all of the six received data fields. The information
in each field is returned exactly as displayed on the CRT. The information is
returned to the control program as a quoted string ("This is an example.").
The received data fields are read only data fields.
The :RCDD1? through :RCDD6? query commands are used to read the contents
of the six received data fields.
