Syntax Found = object.WaitForSilence(SilenceTime, [Timeout], [Options])



Wait for a specified period of datacomm "silence" (no incoming characters).

When waiting from an external application (such as stand-alone Visual Basic), the ProcessDatacomm property should be set to False to prevent Reflection from reading and processing characters between calls to Reflection methods.


SilenceTime Argument Type: String
Specifies the interval of datacomm silence to wait for. The string is specified in HH:MM:SS.hh format. If SilenceTime is 0, this method returns immediately, with Found set to True.

Timeout Argument Type: String
Specifies the amount of time to wait for the period of datacomm silence. The string is specified in HH:MM:SS.hh format. If this argument is omitted or is an empty string (""), Reflection waits forever if a sufficiently long period of silence does not occur.

Options Argument Type: Enumeration
Specifies additional, non-default behavior for the method. There are two options for this method:


 Specifies that the user is allowed to enter keystrokes in the terminal window during the wait.


 Specifies that incoming datacomm characters should not be displayed in the terminal window during the wait.

 You can combine the two options using the addition operator (+): rcAllowKeystrokes + rcNoDisplay.


Found Return type: Boolean
This method returns True if the specified period of datacomm silence was observed, or False if datacomm silence was not observed before the Timeout expired. If no Timeout is specified, this method cannot return False.
