Change the value of the SRQ mask. This command changes the serial
poll enable register of the SR810. The serial poll byte is that of the
SR810 not the SR510! Programs which query the SR510 status
need to be changed to query the equivalent SR810 status byte.
Not implemented. Do not use.
Set or query the auxiliary analog ports. If n=1,2,3 or 4, the value of Aux
Input n is returned. If n=5 or 6, then the Xn,v sets the value of Aux
Output 1 or 2 to v Volts. The X5 ratio is NOT implemented. Ratio
outputs must be done using the SR810 display ratio mode.
Not implemented. Do not use. Use the SR810 status commands to
read the SR810 status bytes.
Reset the SR810. The instrument is reset to the SR810 default setup
listed in the Operation section. This differs slightly from the SR510
default. (The sensitivity is set to 1 V, not 500 mV).
