Before you begin trying to work with this component I recommend that you make sure you can
communicate with your target device using a terminal program. Make sure you understand what
settings your device requires and what commands it expects. There are probably dozens of these
programs at your favorite shareware site.
This component currently does not have the ability change flow control settings (Hardware, Xon/Xoff, etc).
When a port is opened it should default to whatever flow control settings were last used to open
the port or to the default settings. Implementing it should not be difficult if you have a good handle on how
flow control works. It should only involve changing some of the Device Control Block (DCB) settings
the same way I currently change Baud, Parity, etc. Deciding which ones and in what order would be
the tricky part. The following docs may help you out.
Please Do not email me asking for help on how to use this component. Post your questions
