RS232:HARDFlagging
RS-232/Centronics Hardcopy Interface Only
Sets or queries the input and output hard flagging over the RS-232 port. It uses
the RFR (Ready For Receive) and CTS (Clear To Send) lines to control data
transmission. On output, the oscilloscope transmits data only when CTS is
asserted. When CTS is not asserted, the oscilloscope stops transmitting data. On
input, it asserts RFR until the receive queue is full. Then it unasserts RFR to stop
transmission from an external printer. CTS remains unasserted until the receive
queue is not full. At that time, CTS is asserted again to restart transmission.

RS232:HARDFLAGGING ON
turns on hard flagging.
RS232:PARity
RS-232/Centronics Hardcopy Interface Only
Sets or queries the parity used for all RS-232-C data transfers. Parity adds a bit
to the character sequence. When parity is odd or even, the digitizing oscilloscope
generates the selected parity on output and checks all input against the selected
parity. When parity is none, the digitizing oscilloscope performs no input parity
error checks and generates no output parity.
