ESC S Queries the instrument’s status byte
(”ESC” = ASCII 0x1B)
Command = ESC S<CRLF> -> Answer = m<CRLF>
Status byte m is output in decimal notation.
See section 7.6, “Status Byte Format.”
H
Sets or queries the output data header of the OD and OM commands
Command = Hm<CRLF> -> Answer = Hm<CRLF>
Command = H?<CRLF> -> Return = Hm<CRLF>
Parameters

1: With headers
HD
Holds or queries the measurement value display
Command = HDm<CRLF> -> Answer = HDm<CRLF>
Command = HD?<CRLF> -> Return = HDm<CRLF>

1: Display hold
IM
Sets or queries the status byte detection/mask.
Command = IMm<CRLF> -> Answer = IMm<CRLF>
Command = IM?<CRLF> -> Return = IMm<CRLF>

If IM0 is specified, all information bits are masked.
If IM63 is specified, the current operating status is applied to all information bits.
Parameter m = 0 to 63
1: Detect bit 0 (measurement end)
2: Detect bit 1 (output change end)
4: Detect bit 2 (syntax errors)
8: Detect bit 3 (over-range)
