Using the Redirector :: Advanced Options

Always Limit Data Rate to COM Port Baud Rate

The Serial/IP Redirector can be configured to limit the data rate to the baud rate that is in effect for the virtual COM port.

To change the setting

In the Serial/IP Control Panel:

Click Advanced.
Select the Options tab.
Select the Always Limit Data Rate to COM Port Baud Rate check box.
Click OK to record the setting.

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

Settings

Enabled

The redirector will throttle its output data rate to not exceed the baud rate that is currently in effect on the virtual COM port.
There is no effect on input data rate.
If the virtual COM port is connecting to a server that supports COM Port Control, this setting has no effect.

Disabled (default)

The output (and input) data rate are not artificially limited by the redirector.

Tips

Since the Serial/IP Redirector is relaying data to the server over a network connection, the rate at which it sends data to the server can be network speed until various buffers fill in the local computer, the network, and/or the server software. Consequently, the application using the redirector may incorrectly assume that all data has been sent by the serial device because all writes to the virtual COM port have completed. This is not a problem for most applications.

If the server supports the COM Port Control protocol, the server is able to exercise control over the rate at which the redirector sends data. Otherwise, if this option is disabled, the redirector ignores that baud rate setting and lets the server accept data as quickly as it can.

Notes

Applications can change the baud rate of a virtual COM port using the standard COM port API.

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

Currently open ports are unaffected.
