I need to implement a COM port and Modem on top of my USB bulk driver.

I already have made my USB driver. But I have no clue as how to establish the relation with a standard COM port and modem.

Can anyone point me in the right direction?

Regards,
Denis Co

0) Write two more INFs where your driver belongs to the Modem or
Ports setup classes

1) Register for the modem or COM port device interfaces

2) Create a DOS symlink to your COM port number, pulling this value
from the registry where it was placed by the class installer

3) Create a read buffer in your driver and fill it with data that you
are always reading from your device

4) Implement all the serial IOCTLs and timeout semantics
