STAN "7 wire" DTR/RTS control.
Description:
Controls the DTR (Data Terminal Ready) or RTS (Request To Send) line of the
EIA-232-D (RS-232-C) interface. This command has the same effect as selecting
"3 wire" or "7 wire" via front panel control. The RTS (Request To Send) line control
is coupled to the DTR (Data Terminal Ready) line control.
After a
*
RST command, the DTR/RTS control remains unchanged.
After power on, the oscilloscope is in its local state (controlled via front panel).
Example:
Send
→ SYSTem:COMMunicate:SERial:CONTrol:DTR ON Selects the "3
wire" control.

The SYSTem:COMMunicate:SERial:CONTrol command is the remote equivalent
of the front panel REMOTE SETUP - RS232 SETUP option of the UTILITY menu.
