The Set Extended Output And Handshake Mode; Instruction, Esc . N - HP 7470A Interfacing And Programming Manual

<ASC> . . . <ASC> The fourth parameter is optional and defaults to
13, the decimal equivalent of the single ASCII character,
carriage return.
If included, the parameter may be the decimal equiva­
lent(s) of one or two ASCII characters in the range 0 to
127.This becomesthe output terminator. The value 0
is not transmitted and will terminate the string. If a
parameter follows, the semicolon must always be in­
cluded, even when this parameter is omitted. If the fifth
parameter is specified, this fourth parameter must con­
sist of two characters, or the second character must be
specified as null using the semicolon.
H
<ASC> The fifth parameter is optional and, if omitted, assumes
its default value 0 (no output initiator character). If
included, it is the decimal equivalent of a single charac­
ter which becomesthe output initiator character. The
parameter may be the decimal equivalent of any ASCII
character in the range 0 to 127. The parameter is fol­
lowed by a colon.

The Set Extended Output and Handshake
Mode Instruction, ESC . N
DESCWPHUN The set extended output and handshake mode instruc­
tion, ESC . N, establishes parameters for the plotter's communication
format.
USES The instruction is used to specify an intercharacter delay in
all handshake modes, the immediate response string for enquire/
acknowledge handshake, or the Xoff trigger character(s) for the Xon­
Xoffhandshake.
SYNTAX . N [ (<DEC>) ; (<ASC>(; . . .<ASC>)) 1;
DEFAULT . N : No intercharacter delay and no Xoff trigger char­
acter or immediate response string.
EXPLANATIONA colon must be used following the last parameter.
Use of the instruction without parameters is equivalent to ESC . N:
(see DEFAULT).
