RAW command
Purpose
Allows you to set the console device in "raw" mode, which may
result in signifcant gains in display output speed.
Format
RAW [ON | OFF] [/i]
Installation
To install RAW as a PCED user-installed command, just issue the
DOS command:
RAW /i
You can set RAW ON at the time of installation by adding the "ON"
parameter ("RAW ON /i"). RAW uses approximately 700 bytes of
memory when installed.
Remarks
DOS allows console I/O (screen output, keyboard input) to be
performed in either "raw" or normal mode. In raw (or "binary")
mode DOS suspends certain types of processing during console I/O.
The DOS Tech Ref specifies that, for example, the following
processing will not be performed when in raw mode:
-- The characters ^C (break), ^P (print), and ^S (scroll
lock) are not checked for.
-- Other control characters are not output in "caret"
format; for example, if ^A is output, you will see a happy
face rather than "^A".
-- Tabs are not expanded.
The exact list of special processing that will be suspended in
raw mode depends on the console device driver that you use.
The benefit of operating in raw mode is that screen output is
faster; in some case, it may be MUCH faster.
To set the console in RAW mode, simply type "RAW ON". To set it
in normal mode, type "RAW OFF". Typing "RAW" by itself displays
the current console mode.
Although it is possible to use RAW.COM without making it a PCED
user-installed command, this is not recommended.
