DTR Property

State of the DTR signal.

Syntax

Public Property Get DTR() As Boolean
Public Property Let DTR(ByVal bAsserted As Boolean)

Remarks

The DTR property sets or retrieves the state of the DTR signal. This is not supported by all hardware. In such a case, calling this property does nothing, and notably does not raise any runtime error.

Note: you have to ensure that the communication port is open using the Open method before calling this property.
