Escape Codes.
Tc get into Escape Code Sequences/Local M:rle, use the
key-cornbination of:
<SHI.FT><ESC>
For instance, the normal corrrrand to turn the printer (91~
rrode) on is:
<ESC> <@>
Sorne Host Systems will not allow the ESC code (lB) to he
echoed. In this case, the only way to turn the Printer on
is to use the special Local M:rle. In order to do this,
press:
<SHIFr> <ESC> <@>
The ESC @would not he transmitted. It would he detected by
the DI'-l and the Printer channel would he enabled.
In sorœ cases, rrore than one letter is c:perated on, but not
transmi tted in the Local M:rle. For example, if \\le wanted to
rrove the Cursor using the ESC = xy sequence, we would press:
< SHI Fr> <ESC> = 15
This rroves the Cursor to the 18th line and the 2200
character on that line. None of these characters are
transmitted to the Host. The DI'-l recognizes that the ESC =
sequence needs two rrore alpha-codes to complete the
sequence. (For details on Cursor Positioning Codes, see
~F.)
