{Notes:
To speed up the display of lots of data, the terminal provides
a lazy display option. If data is arriving at full speed, the
terminal 'saves up' the data it needs to display until either
(a) it receives a certain number of bytes (defaulting to 200
bytes), or (b) until no data has arrived or the keyboard was
not used for a certain amount of time (default 100
milliseconds). This improves the perceived speed of the
terminal display.
The BlinkTime property can be set to 0, meaning no blinking.
This in turn means that text on the display marked as blinking
will not, it'll be 'on' all the time. For efficiency reasons,
the blink rate cannot be set to anything less than 250 milli-
seconds.
The Capture property has only two values on reading: whether
data capture is 'on' or 'off'. It has three possible values on
writing: 'on', 'off', or 'append'. If the value written is
'append' and the current value is 'off', the capture file is
opened in non-sharing mode for appending data and the value of
the Capture property is then set to 'on' (note that if the
file doesn't exist, it will be created). If the value written
is 'append' and the current value is 'on', nothing happens.
A valid value for the CaptureFile property is required to set
Capture to 'on' or 'append'. If Capture is 'on' and the value
of CaptureFile is changed, Capture is set 'off', the internal
file name changed and then Capture is set back 'on'. If you
want to append to the new file in this situation, the user is
responsible for manually setting Capture 'off' before and then
'append' afterwards.
