Answerback Memory Function
The DEC LA120 emulation provides, as an LA120 feature, an
answerback memory (ABM) that can be programmed with a message
of up to 30 characters. If a message is programmed, it is transmitted
when the ASCII character ENQ is received. The ABM is stored in
the printer’s nonvolatile memory and is programmable with an
escape sequence when the ABM load setup parameter (ABM MSG
LOAD) of the LA120 emulation is turned on.
Escape sequence: ESC [ Q text NUL
Hexadecimal: 1B 5B 51 text 00
where: text can contain up to 30 ASCII characters, and the NUL
character is used as the string terminator.
Note: The printer displays an escape sequence error message if text
exceeds 30 ASCII characters. The default message ESC [ ? 2 c is set
to the Product Identification Response.
New Line Mode
This parameter controls how the DEC LA120 emulation responds to
line feed and carriage return commands.
For the CR NEW LINE selection, a line feed is performed in addition
to a carriage return when a carriage return control code is received.
