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.
