Measurement Computing Analyzer488 - Manual (Page 110)

Section 4 Serial Controller
4.16
@@
Sending the system ID command @@ causes the Analyzer488 to return to power-
on conditions. All data buffers are cleared, the ID character is reset to @, and any
software programmable terminators are returned to the power-on defaults.
This is the only command which does not require a serial terminator to execute.
Reset is executed upon receipt of the second @.
When the @@ command is received, the serial port handshake line Request To
Send (RTS) is unasserted. It is asserted when the Analyzer488 is capable of buffering
commands. If XON/XOFF handshake is selected, the software handshake state is
reset.
The @ character, referred to as the 'ID' character, can be changed or disabled by
using the ID command. If it is anticipated that the ID character may be part of the
data
within an OUTPUT or SEND command, it should be changed or disabled.
This command does not have a query option.
