Display Controls Mode
The wireless station does not support the VT220 terminal
display controls mode, which displays control codes as
graphic characters for debugging.
Dynamically Redefinable Character
Set
The wireless station does not support the dynamically rede-
finable character set (DRCS), which is a 94-character set
you can create on the VT220 terminal and down-line load
into the terminal DRCS buffer.
Special Graphics Character Set
The wireless station supports most of the DEC special
graphics character set. The set contains ASCII C0 codes
and most of the GL codes. It also has special symbols and
short line segments. You would normally use these charac-
ters to create a limited range of drawings while working in
text mode.
Table 8-5 shows special graphics characters recognized by
the wireless station. Ignored codes are parsed (removed)
from the data stream with no action taken by the wireless
station. Codes the wireless station ignores and does not
support are also indicated in the table.
