[control] [signal]<cr>
For example:
input: *SR<cr>
output: 22 1<cr>
The command *SR is sent to the standard telnet port 23 at the ip address of the HPDA-
15RMi-S. The instrument responds with string shown above where the control status is 22
and the signal status is 1.
control = 23 = 16 + 0 + 4 + 2 + 1 = [1] [0] [1] [1] [1]
signal = 0 = 0 + 0 + 0 + 0 + 0 + 0 +0 + 0 + 0 = [0] [0] [0] [0] [0] [0] [0] [0] [1]
The control status returned by the instrument means:
DC power is not present.
