RS232?
Returns
The current RS-232 settings.
Examples
RS232? m
ight return the following string:
RS232:BAUD 9600; SOFTFLAGGING
0; HARD FLAGGING 1; PARITY NONE; TRANS MIT:TERMINATOR LF
RS232:BAUd
Sets or queries the RS-232C interface transmission speed. If no flow control
(flagging) is used, commands may be received faster than the oscilloscope can
process them. Also, if a nother command is sent immediately after this command,
without waiting for the baud rate to be programmed, the first couple of characters
may be lost.
Conditions
This command applies to the TDS200, TDS1000, TDS2000, and TPS2000 Series
only.

RS232:BAUd?
Arguments
<NR1> which can be 300, 600, 1200, 2400, 4800, 9600, or 19200.
Examples
RS232:BAUD 9 600 sets the transmission rate to 9600 baud.
RS232:HARDFlagging
Sets or queries the state of RS232 hard flagging. When hard flagging is enabled,
the oscilloscope sends data if CTS (Clear To Send) is asserted. When receiving
data, the oscilloscope asserts RTS (Request To Send) until the input buffer is
almost full. When the oscilloscope no longer asserts RTS, it continues to read
