Using the Redirector :: Advanced Options

Extend Server Connection (ms)

A common Windows programming technique is to hand off a COM port from one process to another. The underlying assumption is that the second process can open COMxx and be connected to exactly the same device. This option causes the redirector to extend its connection to the server (and access to the device) for a designated interval that begins when the virtual COM port is closed by the application.

To change the setting

In the Serial/IP Control Panel:

1. Click Advanced.

2. Select the Options tab.

3. To change the delay time, type a number of milliseconds in the range 1 to 4,294,967,296.

4. To disable the delay:

• Clear the check box Extend Server Connection, or

• Type a 0 or a blank for the delay time.

5. Click OK to record the setting.

This setting affects all Serial/IP COM ports that are subsequently opened.

Settings

Enabled (default, 8000 milliseconds)

• When the virtual COM port is closed, the redirector maintains its connection to the server for the specified number of milliseconds.

• If the virtual COM port is opened (by any application) before the interval ends, it immediately has access to the same modem or serial device as the prior user of the virtual COM port.

Disabled

• When the virtual COM port is closed, the redirector immediately closes the network connection to the server.

 Notes

This is a global setting that affects all Serial/IP COM ports.

Currently open ports are unaffected.

The maximum delay value (a 32-bit unsigned integer) is approximately 4.3 billion milliseconds, which is about 49 days.
