Nokia 12 GSM MODULE REMOTE I/O manual OutputPulseCancel X commands, Outputpulsecancel

X” command. Note that all example control messages in this chapter use the “term123” identifier string and the password property is set off (see Table 13).

The command cancels the timing of the pulse operation and informs the original pulse originator about it. The state of the cancelled output remains the same, as was set with Output_Pulse X command. Thus, it is the timing of the pulse that is cancelled, not the pulse itself.

Table 13. Output_Pulse_Cancel X commands

Command Type	Command	Comments
Output_Pulse_Cancel X	term123	The command cancels
	Output_Pulse_Cancel X	the pulse of output pin X
	Response:
	OUTPUT_PULSE_CANCEL X:
	OK
	Indication to original pulse originator:
	OUTPUT X PULSE
	CANCELLED
	The X refers to output pin number,
	X=1,2,3,4,5,6,7,8,9,all.

Note: When canceling a pulse, the state of the output does not revert to the same as it was before the Output_Pulse X command. The Output_Pulse_Cancel X command cancels the timing on the pulse, not the pulse itself, as can be seen in Figure 10 (the pulse without cancelling can be seen dashed in the figure).
