Offset RW/RO Definition

24 - 25 RW CONOUT Redirection Flag.
26 - 27 RW AUXIN Redirection Flag.
28 - 29 RW AUXOUT Redirection Flag.

2C RW Page Mode. If this byte is set to zero, some CP/M 3
utilities and CCP built-in commands display one page
of data at a time; you display the next page by pressing
any key. If this byte is not set to zero, the system dis-
plays data on the screen without stopping. To stop and
start the display, you can press CTRL-S and CTRL-Q,
respectively.
2D RO Reserved for system use.
2E RW Determines if CTRL-H is interpreted as a rub/del char-
acter. If this byte is set to 0, then CTRL-H is a back-
space character (moves back and deletes). If this byte is
set to OFFH, then CTRL-H is a rub/del character, echoes
the deleted character.
2F RW Determines if rub/del is interpreted as CTRL-H charac-
ter. If this byte is set to 0, then rub/del echoes the deleted
character. If this byte is set to OFF, then rub/del is inter-
preted as a CTRL-H character (moves back and deletes).
30 - 32 RO Reserved for system use.
33 - 34 RW Console Mode. This is a 16-bit system parameter that
determines the action of certain BDOS Console I/O
functions. (See Section 2.2.1 and BDOS Function 109,
Get/Set Console Mode, for a thorough explanation of
Console Mode.)
