Ppp extern appli +connection tcp embedded


I’m developing an application for the
Q24PL with
OS 657c
WIP 3.00.07
that uses a constant TCP/IP connection to a server.
but at the same time i want to use the ppp from an external application (ex: windows)

is it possible to have and a connection to a server(from within the embedded application)
and have the ppp with windows ?

ps. If i do NOT establish a connection from within my embedded application,
the ppp works fine.

is there any solution to make them work simultaneously ?
