NetModem is primarily designed for Dialout usage, it
can also be used to allow modem based server applications
such as pcAnywhere to allow Dialin access on a modem.
Because this could be a security issue, NetModem Server
also has an option to block any incoming modem calls
on some or all modem pools. When using NetModem for
incoming calls, it is important to keep in mind that
when a particular client application holds a COM port
open as it waits for an incoming call, this prevents
other clients from being able to access that particular
COM port (until the COM port is closed).
By enabling Microsoft Remote Access Service (RAS) on
the NetModem Server computer, you can allow the same
modem pool to be used for both Dialout (handled by NetModem),
and Dialin access to your network (handled by RAS) without
any conflicts. Before NetModem provides a shared modem
to a user, it will first ask RAS if a modem is currently
not in use. If RAS responds that a modem is available,
NetModem will borrow it from RAS and provide it to the
client user. After the users application closes that
modems COM port, NetModem returns the modem to RAS so
it can be used for Dialin again.
To allow NetModem Server to share modems with RAS, you
must enable the 'Support RAS Sharing" checkbox found in the NetMmodem Server pool properties.
