MDR Requests the instrument model name and firmware code (16 ASCII chars).

GLP Requests the calibration data record.

The answer string contains:

• the number of calibrated buffers (1 char)

• calibrated buffer unit (0 = %, 1 = mg/L) (1 char)

• buffer value including sign and decimal point (6 chars)

• calibrated buffer unit (0 = %, 1 = mg/L) (this value is sent only

if there is a 2 point calibration) (1 char)
