The optional parameter n identifies which variation of the Direct Control
state will be used.
n=1 provides the same processing as n=2.
n=2 means that legitimate line 21 control codes are aligned and delayed
so that the two byte control code pairs are transmitted in the same
field.
n=3 means that legitimate line 21 control codes are aligned and delayed
so that the two byte control code pairs are transmitted in the same
field. Each control code pair is sent twice.
n=4 provides the same processing as for n=3. No non-line 21 codes are
transmitted and the control codes are converted (if necessary) to
the correct equivalent code for the current video field.

Real Time State

In Real Time state, incoming data from the caption computer is transferred
as it is typed into the appropriate data stream. The line may be edited
using ^H (backspace) or ^X (delete line). A delay of 1 to 9 seconds can be
inserted by including ^Bn into the data (n is the number of seconds of delay
desired).
If a caption data channel is specified, captions will be in rollup format with a
specified number of lines. The default format is 3 line caption rollup for
caption data channels, and text format for text channels.
When the data channel is put into the real time state, upstream data on the
specified channel will be blocked from entering the output queue of the
encoder. All subsequent data is part of the data stream until ^C is received
or the encoder is reset. If the specified data stream is a text channel,
articles will be suspended from the output queue while the real time state is
active. All caption information in the non specified data channels will be
passed through.
Real Time state is normally terminated by a ^C. Articles will be re-enabled
into the output queue starting with the suspended article. If upstream data
