Command DART 200 DART 300
&E[n]
Escape Code Recognition
Controls handling of the escape character
sequence: enabled or disabled, and whether or
not to forward the sequence to the network.
Escape Code Recognition
TDES is disabled by setting the escape
character in S2 to a value >127.
TIES is disabled using +WS60=0.
The DART 300 always filters the escape
sequence from the data stream.
The DART 200 equivalents are:
DART 200 TDES TIES
&E0 S2=128 +WS60=0
&E1 -none- -none-
&E2 S2=43 +WS60=1
