Serial Poll Status Byte (STB)

The Calibrator sends the serial poll status byte (STB) when it responds to a serial poll.
This byte is cleared (set to 0) when the power is turned on. The STB byte is defined as
shown in Figure 5-9. If you are using the RS-232 as the remote control interface,
transmitting the ^P character (in the Terminal mode, hold down the <Cntl> key and press
P) returns the SPLSTR (Serial Poll String) and the status byte. Refer to the *STB
command, and for RS-232 interface operation, the SPLSTR and SPLSTR? commands, in
Chapter 6 for more information.
