The Set Output Mode Instruction, Esc . M - HP 7470A Interfacing And Programming Manual

The Set Output Mode Instruction, ESC . M
UESCRIPHUN The set output mode instruction, ESC . M, establishes
parameters for the plotter's communication format.
m The instruction is used to establish a turnaround delay, an
output trigger character, an echo terminate character, and an output
initiator character. It is also used to change the output terminator from
its default value, carriage return.
SYNTAX . M [ (<DEC>) ; (<ASC>) ; (<ASC>) ; (<ASC>( ; (<ASC>))
; (<ASC>) ] :
DEFAULT . M: Sets the carriage return character (decimal equiva­
lent 13) as the output terminator. It also specifies that there is no
turnaround delay and no output trigger, echo terminate, or output 1
initiator character .
EXPLANATIUNA colon must be used following the last parameter (if
any). Use of the instruction without parameters is equivalent to
ESC . M: (see DEFAULT).
A description of the instruction's parameters follows.
<DEC> The first parameter is optional. If present, it is the
turnaround delay. The delay implementedis ((parame
ter >< 1.1875)mod 65 536)/ 1.2 milliseconds. The parameter
range is 0 to 54 612. If parameters follow, the semicolon
must be included even if this decimal parameter is
omitted.
<ASC> The second parameter is also optional and, if omitted,
assumes its default value of 0 (no trigger character). If
included, it specifies a single character which becomes
the output trigger character. The parameter may be
the decimal equivalent of any ASCII character in the
range 0 to 127.If parameters follow,the semicolon must
always be included, even when this parameter is omitted.
<ASC> The third parameter is optional and, if omitted, assumes
its default value 0 (no echo terminate character). If
included, it specifies a single character which becomes
the echo terminate character. The parametermay be
the decimal equivalent of any ASCII character in the
range 0 to 127.If parameters follow, the semicolon must
always be included, even when this parameter is omitted.
