Description
When the power is turned on, the terminator or End Of String (EOS) character
(see EOI description, paragraph 3.28.1) is the ASCII line feed 'LF'. If the GPlB
controller does not look for the end message (EOI line low), and it does not
recognize the line feed (LF) as a string terminator, a new EOS character will be
needed. The EOS terminator may be changed to any ASCII character (except IVUL)
by sending 'XV' followed by the decimal value (of the ASCII code) corresponding
to the new terminator.
The character 'C' followed by a single digit code between 0 and 8selects standard
waveform which is inserted between start and stop addresses.

The character 'B' followed by a single digit code between 0 and 4 selects the
operating mode of the instrument.This is the same as the MODE soft key.

The character 'Q' selects generator triggering or gating on the rising or falling
edge of the Trig In ( T L ) signal or GPIB 'J' (positive slope) or 'H' (negative slope)
command. See TRlGGERlNGlGATlNG CHART below.
