SECTION 9 " Extended Commands
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 9-15
Examples of Transmit Only
Extended command characters can be started by an APC
sequence and ended by an ST sequence, or started by a
space and ended by a “#” character.
APC and ST Sequences
When control character sequences for APC and ST mark
data, all of the data is on Line 1. A “#” character is before
the sequence for ST at the end of the line. Control charac-
ter sequences are not displayed, which results in a faster
transmission rate. Also, the cursor position is not lost.
The following example shows data started and ended by
control character sequences. Sequences are prefixed by the
notation “ ^ ” which represents “control.”

Space and “#” Character
The following example shows a space as the start of the
data and a “#” character as the end. The data is on two li-
nes. A “b” indicates a space.
