Ok, I'm working now in the internal "proxy" (a service) that controls all modems and export an interface (Local TCP-IP) to all other applications that require the use of them.  It's clear that this solution will resolve my problem but I dont understand why this limitation at modem driver that forces me to include another intermediate process without work (only a bridge) in all my modems operations.

Thanks.

The MD DLL works with one (single) process only, control / access  multiple Hi-Phone devices.

If some software design requires multiple processes (applications, exe)
to access multiple Hi-Phone devices, then
- A single process will be a server that can control / access multiple Hi-Phone devices.
   This process works with MD DLL API from its one 'end'.
   From its other 'end', it communicates with client processes,
   using any preferred IPC (Inter Process Communication).

- A multiple clients processes can communicate (IPC) with the server process
   so they can all control / access multiple Hi-Phone devices.

Hi all,

 We need to control diferent Hi-Phone USB Desktop Lite modems installed in the same PC with diferent applications, one by each.

 We are making some tests and when the second application calls to InitializeDriver it returns "already initialized" and subsequent calls to other functions (as GetNumdevs) from this second application always return error driver not initialized. Hi-Phone log tells something as "Error, Single proccess please". It seems that first application locks the driver and we must to control all modems installed in the equipment with the same application (I dont understand why this limitation if all other api calls are refered to an specific modem id).

Are there any method to access every modem from a diferent application? 

Many thanks.
