Using Virtual COM Ports
Direct Access as COM Ports
To use virtual COM ports directly from the application, find the settings, preferences, or options in the application that will allow configuration of the COM ports that are going to be used. Virtual COM ports will appear, along with any local hardware COM ports.
Select the virtual COM ports to access the device on the serial server. The application will now be able to use this COM port in the same way that it would use a local COM port.
Some older Windows applications will not recognize COM ports higher than COM4. If using such an application, then create virtual COM ports in the COM1-4 range.
A common programming error may cause the application to fail when attempting to open COM10 and above. These applications will be limited to using virtual COM ports COM1-COM9.
