     Display Temperature, D,[DevSelect]

  Description:
    This commmand displays the temperature of the specified device (preamp or thermistor).

  Input Parameters:

    0 - not used.
    
        This parameter is not currently used.  For the legacy ST10 code, entering
        this parameter forced the cert temperature to be equal the current temperature.
    
          Type:    None
    
          Range:   None
    
          Default: None
    
    1 - Device Select.
    
        This parameter selects the device for which the temperature is to be displayed.
    
        If this parameter is equal to 2, the Preamp temperature will be displayed
        If this parameter is equal to 3, the Channel empearture will be displayed
        Otherwise the Thermistor temperature will be displayed.
    
          Type:    Unsigned 8-bit value
    
          Range:   0 to 0xFF
    
          Default: 0 (Display Thermistor temperature)
    
    2 - not used.
    
        This parameter is not currently used.  For the legacy ST10 code, if this
        parameter was equal to 0x22, the temperature value was written to the disk with
        the Adaptive parameters.
    
          Type:    None
    
          Range:   None
    
          Default: None
    
  Output Data:


    If an error occurred, the following information will be displayed.
    
          "DiagError aaaaaaaa"
    
       where
    
          aaaaaaaa is the Diagnostic Error Code
    
    If no error occurred and the Channel temperature was returned, the following message
    will be displayed.
    
          "Channel temp cccc, CCd"
    
       where
    
          cccc is the temperature value obtained from channel (hexadecimal)
            CC is the temperature value obtained from channel (decimal)
    
    If no error occurred and the Preamp temperature was returned, the following message
    will be displayed.
    
          "Preamp temp cccc, CCd"
    
       where
    
          cccc is the temperature value obtained from preamp (hexadecimal)
            CC is the temperature value obtained from preamp (decimal)
    
    If no error occurred and the Thermistor temperature was returned, the following
    message will be displayed.
    
          "Ref voltage dddd Thermistor voltage eeee Thermistor temp in degrees C ffff, FFd"
    
       where
    
          dddd is the A to D Reference Voltage
    
          eeee is the Thermistor Voltage
    
          ffff is the Thermistor Temperature in degrees Celsius (hexadecimal)
            FF is the Thermistor Temperature in degrees Celsius (decimal)
    
  Revision History:

    0001.0000   Initial revision.
    0011.0000   Combined the PSG Diagnostic Error Codes (PSGDEC) and the Diagnostic External
                Test Service Error Codes (DETSEC) into a single set of Diagnostic Error Codes
                (DiagError).
    0012.0000   Added Temperature in degrees Celsius (decimal) to output.
