Hi,
I need to implement a filter in the COM port stack.
This filter (API) should be able to modify the string sent by an application A to a modem (I do not have any control of the application A, so I need to intercept information in the COM port). The modification is done by an application B connected to the filter ( In the same way, the information coming from the modem shoud be modified by the application B before it is has been sent to the application A).
On the other hand, the application B should be able to communicate with the modem without responding to A (One request from A could produce several B requests to the modem before responding to A)
Do you know if there is some work done or an available tool to answer to such a problem?
Thanks very much for your help.
