DTREnable

This property determines whether to enable the Data Terminal Ready (DTR) line during communications. Typically, a computer sends a DTR signal to its modem to indicate that the computer is ready to accept incoming transmission.

Syntax

object.DTREnable [ = value]

Parameters

object

Object expression that evaluates to a Comm control.

value

Boolean expression that specifies whether to enable the DTR line. Following are the settings for value:

True

Enable the DTR line

False (default)

Disable the DTR line

Remarks

When the DTREnable property is set to True, the DTR line is set to high (on) when the port is opened and low (off) when the port is closed. When DTREnable is set to False, the DTR always remains low.

In most cases, setting the DTR line to low terminates the telephone connection.
