Visual Basic: MSComm Control
Determines the state of the Data Set Ready (DSR) line. Typically, the Data Set Ready signal is sent by a modem to its attached computer to indicate that it is ready to operate. This property is not available at design time and is read-only at run time.
The object placeholder represents an object expression that evaluates to an object in the Applies To list.
The DSRHolding property returns the following values:
|True||Data Set Ready line high|
|False||Data Set Ready line low|
This property is useful when writing a Data Set Ready/Data Terminal Ready handshaking routine for a Data Terminal Equipment (DTE) machine.
